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...

PA6-LGF PA6 modified plastics use pure PA6 as the matrix and enhance internal and external properties through blending, filling, strengthening, copolymerization, crosslinking, and other methods. They account for approximately 15% of PA6 applications. Long glass fiber content ranges from 20%–60%, adjusted according to product requirements, providing high strength, superior heat resistance, good impact resistance, and lightweight alternatives to certain metals. Common applications include power tool shells, garden tools, gears, sports equipment, and automotive parts. Other Specifications of PA6-LGF Flame Retardant PA6: PA6 is naturally flammable, but adding flame retardants changes its combustion properties. Mechanical mixing incorporates nitrogen, phosphorus, bromine-based, or mineral flame retardants. These materials are suitable for switches, low-voltage electrical housings, wiring terminals, and circuit breakers. Toughened PA6: Incorporating toughening agents improves low-temperature resistance, flexibility, fluidity, reduces shrinkage and water absorption, enhances impact and aging resistance. Ideal for baby carriage parts, rolling belts, line clips, and connectors. Applications Beyond daily applications, PA6 modified plastics are increasingly used in high-end fields such as rail transit, medical devices, military, and aerospace. TDS for Reference Nylon reinforced materials are made from PA6/PA66 resins with 20–60% glass fiber to increase strength. 30% fiber content is most common, but 40–50% can be used based on product requirements. Advantages of Long Glass Fiber Compounds 1. High-temperature resistance improves significantly after glass fiber reinforcement, especially for nylon plastics. 2. Shrinkage decreases and rigidity increases due to limited polymer chain movement. 3. Stress cracking is reduced and impact resistance improves. 4. Mechanical properties such as tensile, compression, and bending strength are enhanced. 5. Flame retardancy improves; most reinforced materials become self-extinguishing.
