Polyamide series Nylon is the common name of polyamide (PA), is the general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule, including aliphatic polyamide, aliphatic aromatic polyamide and aromatic polyamide. As the first of the five engineering plastics, nylon has an extremely wide range of industrial applications, mainly used in automotive parts, mechanical parts, electronic and electrical appliances, cosmetics, adhesives and packaging materials and other fields. Among them, aliphatic polyamide, mainly nylon 66, is the most productive and widely used. Polyamide66 Nylon 66 (PA66) is a kind of polyamide formed by the condensation of adipic acid and adipdiamine. The molecular formula is shown in the figure Advantages: high strength, corrosion resistance, good wear resistance, and has self-lubrication, flame retardant, non-toxic environmental protection and other excellent performance. Disadvantages: poor heat and acid resistance, low impact strength in dry state and low temperature, water absorption greatly affects the dimensional stability and electrical properties of products. Long carbon fiber filling PA6 Long carbon fiber is an inorganic polymer material with more than 90% carbon content, which is obtained by carbonization and graphitization of organic fibers. The microstructure of long carbon fiber is similar to that of artificial graphite (C atoms arranged in layers). Advantages: light weight, high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance, electrical and thermal conductivity, etc. Disadvantages: high cost, relatively difficult to infiltrate, poor transparency, defects difficult to check, etc. According to the source of carbon fiber, long carbon fiber can be divided into: Polyacrylonitrile-based long carbon fiber Asphaltic long carbon fiber Viscosified long carbon fiber Long carbon fiber composite material is a very useful structural material, it is not only light, high temperature resistance, but also has a high tensile strength and elastic modulus, is the manufacturing of spacecraft, rockets, missiles, high-speed aircraft and large passenger aircraft indispensable components of the material. It is also widely used in transportation, chemical industry, metallurgy, construction and other industrial sectors as well as sports equipment. Datasheet for reference The density of A66/CF composite material is less than 1.3, which is less than one sixth of the density of steel (7.85), achieving the purpose of lightweight, which is conducive to energy saving and consumption reduction. In the PA66/CF composite system, the length of CF is about 0.5 ~ 0.7mm, the interface between PA66 matrix and carbon fiber is fully combined, and nylon 66 is well wrapped around carbon fiber. The fracture surface of PA66/CF sample is rough, and the PA66/CF composite is a ductile material. Compared with PA66, the mechanical properties of PA66/CF composites are significantly improved.

What is PA66? PA66, abbreviation of Polyamide 66, chemical name polyadiptyl adiptyl diamine, commonly known as nylon 66. Is a colorless transparent semi-crystalline thermoplastic polymer, widely used in automobiles, electronic appliances, mechanical instruments, industrial parts and other industries. What is PA66-LGF? However, due to the large absorbency of nylon itself, poor acid resistance, low impact strength of dry state and low temperature, and easy deformation after water absorption, the dimensional stability of the product is affected, so that its application range is limited to some extent. In order to improve the above shortcomings, expand its application field, and better meet the requirements of performance, people adopt a variety of methods to modify PA66 plastic, so as to improve the impact property, thermal deformation property, forming processing property and chemical corrosion resistance. Because the specific strength and Young's modulus of glass fiber (LGF) are 10~20 times larger than that of PA66, the linear expansion coefficient is about 1/20 of that of PA66, the water absorption is close to zero, and it has good heat and chemical resistance, glass fiber filling is the most commonly used enhancement modification method of PA66. PA66 is the variety with the highest mechanical strength and the most widely used in PA series. Because of its high crystallinity, it has high rigidity and heat resistance. TDS Translucent or opaque opalescent crystalline polymer with plasticity. It has excellent wear resistance, self lubricity and high mechanical strength. Application 1. The automobile industry Because of its excellent heat resistance, chemical resistance, strength and convenient processing, nylon 66 has been widely used in the automobile industry. At present, it can be used in almost all parts of the automobile, such as the engine parts, electrical parts and body parts. The engine part includes the intake system and the fuel system, such as the engine cylinder head cover, throttle, air filter machine housing, vehicle air horn, vehicle air conditioning hose, cooling fan and its housing, water inlet pipe, brake oil tank and cover, and so on. Body parts include: car fender, rear view mirror frame, bumper, dashboard, luggage rack, door handle, wiper bracket, seat belt buckle, interior decoration and so on. Car electric appliances such as electric control doors and Windows, connectors, crisper, cable tie wire. 2. Electronic and Electrical industries PA66 can produce electronic and electrical insulation parts, precision electronic instrument parts, electrical lighting appliances and electronic and electrical parts, can be used to make rice cookers, electric vacuum cleaners, high-frequency electronic food heaters, etc. PA66 has excellent solder resistance and is widely used in the production of junction boxes, switches and resistors. Flame retardant grade PA66 can be used for color TV wire clip, fixing clip and focusing knob. 3. Machinery transportation and machinery and equipment industry PA66 can be used for door handles of passenger cars and brake joint discs of freight cars. Other products such as insulation washer, baffle seat, turbine, propeller shaft, screw propeller and sliding bearing on ship can also be made with PA66. High impact resistance nylon 66 can also be made pipe pliers, plastic molds, radio control body, etc. Unreinforced grade nylon 66 is usually used to manufacture nuts, bolts, screws, nozzles, etc. with low creep and no corrosion. Reinforced grade nylon 66 used in the production of chains, conveyor belts, fan blades, impeller and scaffolding fixed foot buckle.
