Mechanical parts such as automobiles. The market demand for high-strength and high-rigidity nylon is increasing, and new reinforcing materials such as inorganic whisker reinforcement and carbon fiber-reinforced nylon will become important varieties, mainly used in automotive engine parts, mechanical parts and aviation equipment parts.

  At present, the application of nylon 66 has been developed from mainly making tire cord fabrics to the fields of auto parts, electric power and electronic devices. An ordinary car produced in Germany now has a weight of 13 kilograms of nylon 66 injection molded parts for its mechanical parts. China's FAW has established a processing production line for nylon 66 intake manifolds, and the Second Automobile Group is also in preparation. With the technological advancement of the automobile industry, other automobile factories will also adopt nylon 66 intake manifolds one after another. At present, 80% of nylon 66 in China is still used for the production of tire cord fabric, and there is huge room for improvement in the application of nylon 66 in automobiles in the future.

       Nylon alloyed. By blending other polymers, the water absorption of nylon can be improved, the dimensional stability of products, as well as low temperature brittleness, heat resistance and abrasion resistance can be improved. For example, in the Wenzhou-Fuzhou high-speed railway system under construction, 70% of the special nylon 66 plastic fasteners use the products of Huawei Plastic Engineering Company, a subsidiary of Pingmei Shenma Energy and Chemical Group. This is the first time that domestic nylon 66 engineering plastics have been used in It has been applied in the key basic projects of the national high-speed railway. The product has the characteristics of high strength, impact resistance, high rigidity, etc., which also reflects the superior characteristics of nylon 66 as an engineering plastic.

  other applications. Nano nylon has the advantages of higher thermal properties, mechanical properties, flame retardancy and barrier properties than pure nylon; green flame retardant nylon used in electronics, electrical appliances, and electrical appliances has attracted more and more attention from the market; antistatic, conductive nylon and Magnetic nylon, etc., suitable for electronic equipment, mining machinery, textile machinery, etc.
