Polyphenylene sulfide is a new functional engineering plastic.

What is PPS? PPS has a symmetrical rigid backbone and is part of a crystalline polymer consisting of repeated parapplacement of benzene rings and sulfur atoms. PPS are special engineering plastics with high performance, high melting point up to 280℃, which can replace metal. They are located at the top of the polymer property pyramid, as shown in Figure 1. Therefore, based on the excellent performance of PPS resin, make it meet the requirements of harsh engineering plastic projects for materials. Why filling long glass fiber? Long glass fiber reinforced plastic is on the basis of the original pure plastic, adding glass fiber and other additives, so as to improve the scope of use of materials. Advantages: 1. After glass fiber reinforcement, glass fiber is a high temperature resistant material, therefore, the heat resistance temperature of reinforced plastics is much higher than before without glass fiber, especially nylon plastics; 2. After glass fiber reinforcement, due to the addition of glass fiber, limited the mutual movement between polymer chains of plastics, therefore, the shrinkage rate of reinforced plastics decreases a lot, rigidity is greatly improved; 3. After glass fiber reinforcement, the reinforced plastic will not stress crack, at the same time, the anti-impact performance of plastic is improved a lot; 4. After glass fiber reinforcement, glass fiber is a high strength material, which also greatly improves the strength of plastic, such as: tensile strength, compression strength, bending strength, improve a lot; 5. glass fiber reinforced after, due to the addition of glass fiber and other additives, the combustion performance of reinforced plastics decreased a lot, most of the material can not ignite, is a kind of flame retardant material. Datasheets for your reference Performance advantages include the following aspects: excellent heat resistance, good mechanical properties, corrosion resistance, self-flame retardant up to UL94 V-0 level. Because PPS has the advantages of the above properties, and compared with other high performance thermoplastic engineering plastics and has the characteristics of easy processing, low cost, so it becomes an excellent resin matrix for manufacturing composite materials.

PPS The molecular structure of PPS consists of benzene ring and sulfur atoms interarranged, the configuration is orderly, easy to form a high thermal stability of the crystal structure. At the same time, the molecular structure of PPS material has a highly stable chemical bond characteristics, the benzene ring structure makes PPS more rigid, and the sulfur ether bond (-S-) provides a certain degree of flexibility. PPS itself has good heat resistance, flame retardant, chemical resistance, should be a promising material, but unmodified PPS has some unavoidable defects: Difficult processing:  This is the biggest pain point of all high temperature resistant materials -- high processing temperature, no matter the molding process or processing energy consumption, will face great challenges. In addition, PPS is still prone to thermal oxidation crosslinking in the melting process, resulting in reduced fluidity and further improve the processing difficulty; Poor toughness: PPS molecular chain is rigid, the maximum crystallinity is as high as 70%, the elongation is low and the welding strength is not so good. As a result, the impact resistance of unmodified PPS is poor, which limits the application scope. High cost: PPS raw materials and general engineering plastics compared, the price is about 1-2 times higher, and some modified materials compared with low cost performance; Difficult coating: PPS surface coating and coloring performance is not ideal. While this is not a major problem for now, it is a limiting factor. PPS-LGF Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properties of engineering polymers, and increase the durability by forming long fibers to form a long-fiber-reinforced internal skeleton network. Performance is preserved in a wide range of environments. TDS for reference Application About us Xiamen LFT composite plastic Co., Ltd. is a brand-name company that focuses on LFT&LFRT.

PPS Special engineering plastics are engineering plastics with higher overall performance and long-term use temperature above 150℃, PPS is one of them. The carbon fiber reinforced special engineering composites formed by carbon fiber as the reinforcement and these special engineering plastics as the matrix have excellent mechanical properties, wear resistance and high temperature resistance, which can be used in aerospace, marine or medical fields, and in some aspects show more desirable application advantages than thermosetting resins or even metal materials. PPS-LCF Polyphenylene sulfide PPS resin strength and hardness are relatively high, good mechanical properties, adapt to a variety of molding and processing methods, you can achieve secondary precision molding, the dimensional stability of the product is better. Its moisture absorption rate of only 0.03%, low density, melt temperature Tm of 285 ℃, the glass transition temperature Tg of 90 ℃, thermal stability is very good, in the air state, to reach 430 ℃ -460 ℃ before decomposition, high flame retardant grade, 200 ℃ insoluble in most organic solvents, excellent electrical insulation. As a special engineering plastics, PPS advantages are outstanding, but defects also exist, for example, because of the large number of benzene ring to make its impact resistance and elongation is not good enough, but through the carbon fiber reinforced way, can further improve the performance of the material strength and thermal stability, so as to better show the value of the application of the material. Through the carbon fiber reinforced intervention, changing the original insulating properties of PPS into a conductive, anti-static properties, polyphenylene sulfide PPS toughness and strength can be substantially increased and improved, becoming one of the most commonly used composite materials in the aerospace field. It is used in aircraft landing gear, wings, hatches, fuel tank port covers, J-shaped nose cone, cabin interior trim and other components, not only to help increase the impact resistance, high temperature and corrosion resistance of these parts, more through the reduction in mass, to enhance the aircraft load efficiency and reduce fuel consumption. Compared with metal, this composite material has the advantages of low cost and easy processing, the cost can be reduced by 20-50 percent. High bonding must be maintained between the carbon fiber reinforcement and the PPS resin matrix. When the product is subjected to stress, this high bonding helps the interface to transfer the external load to the fibers effectively, which can effectively prevent cracks from debonding between the interfaces, in addition to enhancing the mechanical properties of the composite. To make the resin matrix and carbon fiber reinforcement between the formation of high bonding, we must make the molten state of PPS resin and carbon fiber reinforcement in full contact, full impregnation, so that the fiber body in the case of uniform dispersion to achieve good impregnation effect.

Polyphenylene sulfide PPS is one of the typical representatives of special engineering plastics, with a linear structure of alternating benzene rings and sulfur atoms. In the condensed structure, PPS is easy to crystallize, crystallinity of nearly 70%, therefore, has good thermal stability, chemical stability and dimensional stability, etc. PPS mainly has the following five performance advantages. (1) excellent heat resistance. pps melting point of more than 280 ℃, heat deflection temperature of more than 260 ℃, and after high-temperature heat aging treatment, the strength retention rate is high. (2) since the flame retardant. PPS itself has flame retardant, without adding flame retardants flame retardant level can reach UL94 V- 0 level. (3) good mechanical properties. PPS is a brittle material, has good creep resistance, high surface hardness, good wear resistance, and carbon fiber and other materials compound, but also shows good self-lubricating properties. (4) excellent chemical resistance, irradiation resistance. pps below 200 ℃ almost insoluble in any solvent, can withstand almost all inorganic substances, radiation dose up to 108Gy. (5) good processing properties. pps melt viscosity is low, as the resin matrix of composite materials, for the reinforcement of the flow of excellent wetting effect. As PPS has the above performance advantages, and compared to other high-performance thermoplastic resins and easy processing, low cost, so become an excellent resin matrix for the manufacture of composite materials. Long glass fiber Glass fiber is an inorganic non-metallic material with excellent performance, is a natural mineral with silica as the main raw material, add specific metal oxide mineral raw materials, mixed evenly, molten at high temperature, molten glass liquid flow through the funnel outflow, in the role of high-speed pull gravitational force is drawn and rapidly cooled and cured into a very fine continuous fiber. Glass fiber monofilament diameter from a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber original filament are composed of hundreds or even thousands of monofilaments. Glass fiber basic properties: The appearance of a smooth cylindrical surface, the cross-section is a complete circle, round cross-section to withstand the load capacity; gas and liquid through the resistance is small, but the surface is smooth so that the holding force of the fiber is small, not conducive to the combination with the resin; density is generally in 2.50-2.70 g/cm3, depending mainly on the glass composition; tensile strength than other natural fibers, synthetic fibers to be high; brittle materials, the elongation at break is very small ; water resistance and acid resistance is good, while alkali resistance is poor. It can be divided into continuous glass fiber, short glass fiber (SGF) and long glass fiber (LGF) by length classification. Long glass fiber is the most widely used glass fiber at present. And Xiamen LFT plastic composite company is focuses on the produce of long glass fiber compounds for many years. SGF VS LGF 1. The difference in size length Engineering materials long glass fiber and short glass fiber, literally means the difference in size length; more common short glass fiber size is about 0.2mm-0.6mm between; long glass fiber size is about 6mm-25mm between. 2. Performance strength differences Different lengths of glass fibers are different in their performance strength, the fiber length of long glass fibers in the composite material inside the impact strength than short glass fibers stronger. 3. Production process is different Production of long glass fiber, high requirements for raw materials, especially the manufacturing process requires the surface of glass fiber to be activated, the processing can not be flooded with glass fibers, as well as external leakage phenomenon occurs. Production of short glass fiber, because the size is generally no special requirements, so the production is relatively easy, the requirements for raw materials are not so high, the production costs for manufacturers low. 4. Different production and processing methods Long glass fiber production and processing methods generally use injection molding and molding; while most short glass fiber injection molding method.

PPS Information Polyphenylene sulfide (PPS) is not enhanced before modification, its disadvantages are brittle, poor toughness, low impact strength, after filling glass fiber, carbon fiber and other enhancements modified to overcome the above shortcomings, to obtain very good overall performance. PPS filling Long carbon fiber In the modified engineering plastics industry, long fiber reinforced composites are composites made from long carbon fibers, long glass fibers and polymer matrix through a series of special modification methods. The most important feature of long fiber composites is that they have superior performance that the original materials do not have. If we classify them according to the length of the reinforcing materials added, they can be divided into: long fiber, short fiber and continuous fiber composites. Long carbon fiber composites are one kind of long fiber reinforced composites, which are a new fiber material with high strength and high modulus. It is a new material with excellent mechanical properties and many special functions. Corrosion resistance: LCF carbon fiber composite materials have good corrosion resistance and can adapt to the harsh working environment. UV resistance: the ability to resist UV is strong, and the products are less damaged by UV. Abrasion and impact resistance: the advantage of comparing with general materials is more obvious. Low density: lower density than many metal materials, can achieve the purpose of light weight. Other properties: such as reducing warpage, improving rigidity, impact modification, increasing toughness, electrical conductivity, etc. LCF carbon fiber composites have higher strength, higher rigidity, lower weight, and excellent electrical conductivity compared with glass fiber. PPS TDS for reference PPS Application Other products you can also contact us for more technical advice. Q&A 1. Are carbon fiber composite products very expensive? The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the number of products. The higher the performance of the raw material, the more expensive it is, such as the carbon fiber PEEK thermoplastic material used in orthopedics. Of course, the more complex the manufacturing process, the greater the working time and workload, and the increased production costs. However, the larger the order quantity, the lower the cost per product. In the long run, the superior performance of carbon fiber will extend the life of the product, reduce the number of maintenance, and is also very beneficial to reduce the cost of use. 2. Are carbon fiber composite products toxic? Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other substrates, and are generally not toxic. For example, the above-mentioned PEEK material is made of food-grade resin, which is very compatible with the human body and is not only harmless to humans, but also becomes a more ideal material for orthopedic surgery because of its high strength and elastic modulus close to the bone cortex. Carbon fiber medical bed plate, will be in daily contact with many patients body, will not have adverse effects on the human body, on the contrary, for the accuracy of medical diagnosis and a great help. 3. What is the difference between thermosetting carbon fiber composites and thermoplastic carbon fiber composites? Thermoset carbon fiber composites favor the role of curing agent in curing and molding. While thermoplastic carbon fiber composite products mainly rely on cooling down to achieve the shaping. Thermoplastic carbon fiber composites are not as popular as thermoset carbon fiber composites, mainly because they are expensive and are generally used in high-end industries. Thermoset carbon fiber composites are difficult to recycle due to the limitation of the resin matrix itself, and are generally not considered; thermoplastic carbon fiber composites can be recycled, and can be made twice as long as they are heated to a certain temperature.

PPS material In recent years, the application of special engineering plastics has gradually extended from the previous military and aerospace fields to more and more civil fields, such as automotive, equipment manufacturing, high-end consumer goods, etc.. Among them, polyphenylene sulfide (PPS) and polyether ether ketone (PEEK) are two special engineering plastics that have developed relatively quickly and have a wide range of applications. PEEK is superior to PPS in terms of strength, toughness, and maximum operating temperature. In terms of high-temperature resistance, PEEK is about 50°C higher than PPS. But on the other hand, the relatively obvious cost advantages and better processing properties of PPS make it more widely used. PPS is a crystalline, highly rigid white powder polymer, high heat resistance (long-term use of 200 ℃ -220 ℃, short-term can withstand high temperatures of 260 ℃), is a mechanical strength, rigidity, flame retardant, chemical resistance, electrical properties, dimensional stability are excellent resin. It has excellent wear resistance, creep resistance, flame retardancy and self-extinguishing properties. It maintains good electrical properties at high temperature and high humidity. Good flowability, easy to mold, almost no shrinkage and concave spot when molding. Good affinity with various inorganic fillers. It has been developed to shorten the difference between standard thermoplastic materials (e.g. PA, POM, PET ......) and advanced engineering plastics. PPS has the following distinct performance advantages: (1) Intrinsically Flame Retardant Unlike PC and PA, PPS pure resin and its glass fiber/mineral powder filled composites without any added flame retardants 可以轻松达到V-0@0.8mm甚至更薄厚度的V-0阻燃级别. Although PC and PA have a cheaper price and better mechanical strength (especially impact strength) than PPS, the cost of PC and PA composites with the addition of halogen-free flame retardant formulations (V-0@0.8mm级别) is significantly higher, in many cases even higher than PPS materials with the same mechanical strength. (2) Ultra-high flowability For the semi-crystalline PPS, its very high fluidity can allow glass fiber filling easily more than 50 %, while in the process of high-temperature melt blending extrusion, PPS compared to PC lower viscosity can make the glass fiber to withstand a lower degree of shear and extrusion, so that the final injection molded products have a longer retention length, to further enhance the effect of modulus. (3) Ultra-low water absorption This advantage is mainly for PA. In terms of fluidity, highly filled PA and PPS are comparable; and for mechanical properties, the same amount of filling PA composites will be more advantageous. But in addition to the halogen-free flame retardant limitations, another factor limiting the application of PA is its high water absorption: compared to high-temperature nylon PA6T 0.6%-1% water absorption, PPS 0.03% water absorption rate is almost negligible. The result is that PPS products due to water absorption and deformation of the product defect rate is much lower than the same conditions of PA products. (4) the unique metallic texture and higher surface hardness PPS injection molded parts will be dropped on the table, a very crisp sound unique to PPS crash. Through the special mold and reasonable mold temperature with the PPS injection molded parts in the human touch will also sound similar to the impact of metal, the surface will be as smooth as a mirror, with a metal-like luster. PPS-LCF compounds Length: About 12mm, or customized Color: Original color, or customized Fiber specification: 20%-60% Grade: General grade Long carbon fiber reinforced composites offer significant weight savings and provide optimum strength and stiffness properties in reinforced thermoplastics. The excellent mechanical properties of long carbon fiber reinforced composites make it an ideal replacement for metals. Combined with the design and manufacturing advantages of injection molded thermoplastics, long carbon fiber composites simplify the re-imagining of compoents and equipment with demanding performance requirements. Its widespread use in aerospace and other advanced industrials makes it a "high-tech" perception of consumers. Datasheet for reference Application Factory Q & A 1. Is there a uniform reference data for carbon fiber product performance? The performance of specific carbon fiber filaments is fixed, such as Toray's carbon fiber filaments, T300, T300J, T400, T700, etc. There are a series of parameters that can be traced. However, there is no uniform standard to measure the carbon fiber composite products. Firstly, the different models of raw materials selected will lead to different performance of the products, and then the different selection of substrate and product design will lead to different performance of the products. In addition to some common carbon fiber tube, carbon fiber plate and other conventional parts, most of th...

Polyamide 12 filling long glass fiber The recommended long-term working temperature of polyphenylene sulfide resin (PPS) is 220~240℃. The material has good thermal stability, and its mechanical properties remain at about 80% and 60% of their original values at 100°C, 160°C and 200°C, respectively. The material has excellent creep resistance and fatigue resistance at room temperature. The material also has excellent resistance to acids, alkalis, salts, organic solvents and other media, except for oxidizing acids and strong oxidizing media, and is almost insoluble in any chemical solvent below 170°C. It is especially suitable for hydrofluoric acid, halogenated hydrocarbons and chloride ion corrosion resistance. PPS is a flame retardant material with an oxygen index of 46 to 53, better than most engineering plastics. Polyphenylene sulfide has high resistance and low dielectric constant electrical properties, and can maintain good electrical properties under high temperature and high humidity conditions. In addition, the mechanical properties of the resin material are not very outstanding because it has good affinity with glass fiber, carbon fiber, inorganic filler and solid lubricant, and the modification is good, so the particles used in injection molding are mainly modified and reinforced by various fibers and inorganic fillers. LGF & SGF Nylon particles of ordinary glass fiber: Size size is about 3-4mm, length to width ratio 50-250 Long glass fiber nylon particles: Size is about 10-12mm, aspect ratio >400 In addition, the distribution of glass fiber in the two kinds of particles is also different. Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved. Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved. The rigidity retention rate of long glass fiber is better than that of short glass fiber, and long glass fiber is more resistant to heat aging. The creep performance is affected by time, temperature and load. At 120℃ and 40Mpa load, the creep of long glass fiber is significantly better than short glass fiber. This is critical for parts with long term static pressure, and long glass fiber can be tried when short glass fiber cannot meet the requirements. Shrinkage is crucial to the size of the part. The transverse shrinkage of short glass fiber material is much higher than the longitudinal shrinkage, and the anisotropy is more serious, resulting in difficult to control the size of the part and obvious shrinkage. In contrast, the transverse and longitudinal shrinkage rates of long glass fiber materials are very close, showing isotropy, improving the risk of part warpage and making the dimensions more controllable.
