What is PA6 plastic? polyamide (PA), usually called Nylon, is a hetero-chain polymer containing amide group (-NHCo -) in the main chain. It can be divided into aliphatic group and aromatic group. It is the earliest developed and the most used thermoplastic engineering material. Polyamide main chain contains many repeated amide group, used as a plastic called nylon, used as a synthetic fiber called nylon. A variety of different polyamides can be prepared according to the number of carbon atoms contained in binary amines and dibasic acids or amino acids. At present, there are dozens of polyamides, among which polyamide-6, polyamide-66 and polyamide-610 are the most widely used. Polyamide-6 is an aliphatic polyamide, with light weight, strong strength, wear resistance, weak acid and alkali resistance and some organic solvents, easy molding and processing and other excellent properties, widely used in fiber, engineering plastics and thin films and other fields, but PA6 molecular chain segment contains strong polarity amide groups, easy to form hydrogen bonds with water molecules, The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. Advantages of nylon 6: High mechanical strength, good toughness, high tensile and compressive strength. Outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. High softening point, heat resistant. Smooth surface, small friction coefficient, wear-resistant. Corrosion resistance, very resistant to alkali and most salts, also resistant to weak acids, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, alkaline and so on, and has good anti-aging ability. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and mildew resistance. Has excellent electrical performance, good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can work frequency insulation material, even in high humidity environment still has good electrical insulation. Light weight, easy dyeing, easy forming, because of low melting viscosity, can flow quickly. Disadvantages of Nylon 6: Easy to absorb water, water absorption, saturated water can reach more than 3%. Poor light resistance, in the long-term high temperature environment will oxidize with oxygen in the air, the color turns brown at the beginning, and the subsequent surface is broken and cracked. Injection molding technology requirements more strict, the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. Will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. Why filling Long Glass Fiber? PA6 has excellent properties such as light weight, strong strength, abrasion resistance, weak acid and alkali resistance and some organic solvents, and easy molding and processing. It is widely used in the fields of fibers, engineering plastics and films. However, the molecular chain segment of PA6 contains highly polar amide groups, which are easy to form hydrogen bonds with water molecules. The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. With the development of science and technology and the improvement of life quality, the defects in some properties of traditional PA6 materials have limited its development in some fields. In order to improve the performance of PA6 and expand its application field, PA6 should be modified. Filling enhancement modification is a common method for physical modification of PA6. It refers to the modification of PA6 by adding fillers such as glass fiber and carbon fiber into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material. What is application of PA6-LGF? Modified section of 30% long glass fiber reinforced PA6 is the ideal material for processing power tool shell, power tool parts, engineering machinery parts and automobile parts. Its mechanical properties, dimensional stability, heat resistance and aging resistance have been significantly improved. The fatigue resistance strength is 2.5 times that of unenha...

What is Polyamide 66 materials? PA66, abbreviation of Polyamide 66, chemical name polyhexanediylhexanediamine, commonly known as nylon 66. It is a colorless transparent semi-crystalline thermoplastic polymer, widely used in automotive, electrical and electronic appliances, mechanical instruments and meters, industrial parts and other industries. However, due to the high water absorption, poor acid resistance, low impact strength in dry state and low temperature, and easy to deform after absorbing water, which affects the dimensional stability of the products, the scope of its application has been limited to a certain extent. In order to improve the above shortcomings, expand its field of application, and better meet the requirements for the use of performance, people use a variety of methods to modify PA66, in order to improve the impact, heat deformation, molding and processing performance and chemical corrosion resistance of PA66 plastic. As the specific strength and Young's modulus of glass fiber (GF) is 10-20 times larger than PA66, the coefficient of linear expansion is about 1/20 of PA66, the water absorption rate is close to zero, and there is good heat and chemical resistance, etc., so the glass fiber filling is the most commonly used means of enhancement and modification of PA66.                       Polyamide 66 fillin long glass fiber compounds Why do we use LFT plastics instead of metal? Many components that are currently manufactured in metal can be produced at lower cost and lower weight in high strength plastics. Compared to metals, plastics offer a number of significant advantages: • Faster production cycles • Lower investment in equipment and tooling • Elimination of finishing operations, such as machining or painting • No corrosion problems • Tighter tolerances • Easier assembly What is the difference between Long glass fiber and Stardard glass fiber? Long glass fiber (LGF) typically contain glass fibers with lengths of 10 to 12 mm, versus 0.7-mm fibers in standard glass-reinforced compounds. In the composite material made of fibers is sheared or pulled, the fibers are pulled out from the matrix, such a pulling process is conducive to the absorption of energy provided by the loading, the longer the fibers are within a certain length, the greater the absorption of energy, and the more significant its strength. And in the same volume amount, due to the longer the single fiber, the fewer the number of fiber roots, the less stress concentration generated at the fiber end, the more difficult the destruction of the material. From the results of practical application feedback, the various properties of long glass fiber reinforced thermoplastic composites are more excellent than Standard glass fiber. In addition, glass fiber reinforced composites in the friction process, the fiber body plays an important role in lubrication, long glass fiber can be much more sustainable, stable lubrication, so the coefficient of friction is lower, less wear, and the formation of the abrasive debris is finer. Because of these advantages, long glass-fiber reinforced thermoplastic composites perform better in real-world applications without fear of high frequencies and high loads. What is the advantages of Polyamide 66? Nylon 6/6 is composed of a molecular structure of higher order than Nylon 6, heightening Nylon 6’s positive characteristics: higher tensile strength and stiffness, better dimensional stability, and a higher melting point. Nylon 6/6 has a high lubricity and resistance to hydrocarbons; and exceptionally balanced strength, ductility, and heat resistance.

PP-LGF Glass fiber reinforced PP, usually, the tensile strength of PP material is between 20M~30MPa, bending strength is between 25M~50MPa, bending modulus is between 800M~1500MPa. If PP is to be used in engineering structural parts, it must be reinforced with glass fiber. Glass fiber reinforced PP, through glass fiber reinforced PP product mechanical properties can be multiplied or even several times the improvement. Specifically, the tensile strength reaches 65MPa~90MPa, the bending strength reaches 70MPa~120MPa, and the bending modulus reaches 3000MPa~4500MPa. Such mechanical strength can be completely comparable with ABS and enhanced ABS products, and it is more heat resistant. Glass fiber reinforced PP, general ABS and reinforced ABS heat resistance temperature between 80℃~98℃, and glass fiber reinforced PP material heat resistance temperature can reach 135℃~145℃. PP filling modification, adding a certain amount of inorganic minerals in PP, such as talcum powder, calcium carbonate, titanium dioxide, mica, etc., can improve rigidity, improve heat resistance and luster; Filling carbon fiber, boron fiber, glass fiber can improve the tensile strength; Adding flame retardant can improve flame retardant property. Filling antistatic agent, colorant, dispersant, etc. can improve the antistatic property, colorability and fluidity, etc.; Filling nucleating agent can speed up the crystallization speed, increase the crystallization temperature, form more and smaller spherical crystals, thus improving the transparency and impact strength. Therefore, the filler has a significant effect on improving the performance of plastic products, improving the plastic molding processability and reducing the cost. Application As one of the four general plastic materials, PP has excellent comprehensive performance, good chemical stability, better molding performance and relatively low price; But it also has the strength, modulus, hardness is low, low temperature impact resistance strength is poor, forming shrinkage, easy aging and other shortcomings. Therefore, it must be modified so that it can adapt to the demand of the product. The modification of PP material is generally through adding mineral reinforcement toughening, weather resistance modification, glass fiber reinforcement, flame retardant modification and super toughness modification, and each kind of modified PP has a large number of applications in the field of household appliances. Glass fiber reinforced PP, can be used to make refrigerators, air conditioning refrigeration machines such as axial flow fans and cross flow fans.

PPS information The resin matrix of thermoplastic composites involves general and special engineering plastics, and PPS is a typical representative of special engineering plastics, commonly known as "plastic gold". 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 composite material PPS filling short glass fiber (SGF) composite material has the advantages of high strength, high heat resistance, flame retardant, easy processing, low cost, and has been applied in automotive, electronics, electrical, machinery, instruments, aviation, aerospace, military and other fields. PPS filling long glass fiber (LGF) composite material has the advantages of high toughness, low warpage, fatigue resistance, good product appearance and so on. It can be used in water heater impeller, pump shell, joint, valve, chemical pump impeller and shell, cooling water impeller and shell, household appliance parts and so on. What are the specific differences between short glass fiber (SGF) and long glass fiber (LGF) reinforced PPS composites? 1. Mechanical property analysis The reinforcement fiber added in the resin matrix can form a supporting skeleton, and the reinforcement fiber can effectively bear the external load when the composite is subjected to external force. At the same time, energy can be absorbed by fracture, deformation and other ways to improve the mechanical properties of resin. The tensile strength and bending strength of the composites are gradually increased by increasing the amount of glass fiber. The main reason is that when the glass fiber content increases, more glass fiber in the composite material can withstand the action of external force. Meanwhile, due to the increase in the number of glass fibers, the resin matrix between the glass fibers becomes thinner, which is more conducive to the construction of glass fiber reinforced frame. Therefore, with the increase of glass fiber content, more stress is transferred from resin to glass fiber under external load, which effectively improves the tensile and bending properties of composite materials. The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. When the glass fiber mass fraction is 30%, the tensile strength of PPS/SGF and PPS/LGF composites is 110MPa and 122MPa, respectively. The bending strength was 175MPa and 208MPa, respectively. The flexural elastic modulus were 8GPa and 9GPa, respectively. The tensile strength, bending strength and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9% and 11.3% compared with PPS/SGF composites, respectively. PPS/LGF composites have higher length retention rate of glass fiber. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties. When the glass fiber content is low, the impact strength of the composite decreases. The main reason is that the lower glass fiber content cannot form a good stress transfer network in the composite material, so that the glass fiber exists in the form of defects under the impact load of the composite material, resulting in the overall impact strength of the composite material is reduced. With the increase of the glass fiber content, the glass fiber in the composite can form an effective spatial network, and the reinforcement effect is greater than that of the glass fiber tip. Under the action of external load, the external load can be transferred to the reinforced fiber better, thus improving the overall performance of the composite. In the PPS/LGF system, the length of the glass fiber is longer and the spatial network is more dense. The reinforced glass fiber has greater bearing capacity and better impact strength. When the mass fraction of glass fiber is 30%, the impact strength of PPS/LGF is increased by 19.4% from 31kJ/m2 to 37kJ/m2, and the notch impact strength is increased by 54.5%(from 7.7kJ/m2 to 11.9kJ/m2). 2. Thermal properties analysis of PPS/SGF and PPS/LGF composites When the mass fraction of glass fiber is 30%, the thermal deformation temperature of PPS/SGF composite and PPS/LGF composite reaches 250℃ and 275℃, respectively. The thermal deformation temperature of PPS/LGF composite is 10% higher than that of PPS/SGF composite. The main reason is that the introduction of glass fiber makes the network skeleton of reinforced fiber formed inside the composite material, which greatly improves the heat resistance of the composite material. The size of glass fiber in PPS/LGF is longer, and the heat resistance improvement advantage is more obvious....
