Polyamide 66 Nylon 66 (PA66) has excellent mechanical properties, processing performance and corrosion resistance, after flame retardant modification of PA66 can be widely used in automotive, electronics, machinery and other fields. With the wide application of nylon in different fields, the requirements for its performance have been taken to the next level. However, PA66 has high crystallinity and fast crystallization speed, and is prone to warpage defects during injection molding process. Especially for glass fiber reinforced nylon 66, due to the anisotropic arrangement of glass fibers inside the material, it is easy to cause different shrinkage rates in all directions, which further aggravates the warping deformation. Long glass fiber reinforced composites Glass fiber is an excellent performance of inorganic non-metallic materials, mostly used for reinforcing plastics. Mainly silica as raw material, add specific metal oxides mineral raw materials melted at high temperature, molten glass liquid flow through the leakage nozzle out of the role of high-speed pulling gravitational force is drawn and rapid cooling and curing into a very fine continuous fibers, the diameter of a few microns to more than twenty microns. Glass fiber is divided into short glass fiber, long glass fiber according to the shape. Short glass fiber: length less than 6mm, cross-section is round, in the material distribution disorder, anisotropy. Long glass fiber: length between 6-25mm, orderly distribution in the material, isotropic. Short Glass Fiber Nylon: Processability, rigidity and strength are improved, and floatation is less likely to occur during injection molding compared to long glass fiber nylon. Long glass fiber reinforced nylon: less anisotropic shrinkage compared to short glass fiber, reducing the effect of warpage. The rigidity, abrasion resistance, aging resistance, and heat resistance are stronger than those of short glass fiber reinforced nylon.

Introduction of Nylon66 filled LCF pellets PA66 is a high-performance engineering plastics, moisture absorption, poor dimensional stability of products, strength and hardness and metal. In order to overcome these shortcomings, as early as the 1970s, people use carbon fiber and glass fiber to enhance to improve its performance. PA66 reinforced with carbon fiber fiber materials in recent years the development of faster, because PA66 and carbon fiber are excellent performance in the field of engineering plastics materials, the composite material comprehensive embodiment of the superiority of the two, such as strength and rigidity than the unenhanced PA66 is much higher than that of the high-temperature creep is small, the thermal stability of a significant improvement in the dimensional accuracy of the good, wear-resistant.

Compared with glass fiber, the modulus is 3 times higher, which is a material with high rigidity and high strength. Datasheet of PA6-LCF for reference From the experiments of the technical department, we know that the bending strength, bending modulus of elasticity, impact strength and plane shear strength of the carbon fiber PA66 fiber-added material increase with the increase of carbon fiber content, transverse shear strength slightly decreased, overall the strength of the material has increased dramatically. Application of PA66-LCF Certificate Quality Management System ISO9001/16949 Certification National Laboratory Accreditation Certificate Modified Plastics Innovation Enterprise Honorary Certificate Heavy metal REACH & ROHS testing Factory & Lab Q & A 1. Is there a unified 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 and so on, there are a series of parameters can be traced. However, there is no uniform standard to measure the carbon fiber composite products. Firstly, the different types of raw materials selected will lead to different performance of the products, and then due to the choice of matrix and the different design of the products, it will lead to different performance of the products. In addition to some common carbon fiber tubes, carbon fiber boards and other conventional parts, most of the carbon fiber products in the production of the sample before the test to determine whether the performance of the product is in line with the use of the expected standard, and as a base point, so as to carry out the production and use of large quantities. 2. Are carbon fiber composite products expensive? The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the quantity of products. Some products of the industrial environment requirements are high, the performance of carbon fiber products and materials have special requirements, which requires the selection of specific raw materials, raw materials, the higher the performance of the natural price of the more expensive, such as the application of orthopedic carbon fiber PEEK thermoplastic materials. Of course, the more complex the production process, the greater the working time and workload, and the production cost increases. However, the larger the order quantity, the lower the cost per piece, once the mass production of a particular carbon fiber product has been established. In the long run, the superior performance of carbon fiber will prolong the service life of the product, reduce the number of maintenance, and is also very beneficial to the reduction of the cost of use. 3. Are carbon fiber composite products toxic? Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other matrices, generally not toxic. For example, the above mentioned PEEK material is a food grade resin, this material has good compatibility...

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 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. As strong as it is independently, adding fillers, fibers, lubricants, and impact modifiers can increase Nylon 6/6’s strength times five and stiffness times ten.                       TDS of 30% long stand fiber glass reinforced Polyamide 6.6                  All TDS with 20%-60% fiber specification, please aks technologists What are the applications of Nylon 66 filling long stand fiber glass pellets?

TDS Tested by us, for reference only. Application Injection technology About us Come and contact us now!

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...
