Consumption structure of nylon 66

In 20 12 years, the consumption structure of nylon 66 in China is: machinery 3 1%, electronics 30%, automobiles 20%, packaging 12%, textiles 4% and others 3%. In the second half of 20 12, especially in July, the price of raw material caprolactam was also falling due to the sluggish demand of downstream nylon textile industry. Most spot buyers hold a wait-and-see attitude, and few people purchase goods.

The main uses of modified nylon products are as follows:

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

At present, the application of nylon 66 has developed from mainly making tire cord fabric to the fields of automobile parts, power and electronic devices. Now an ordinary car produced in Germany, the weight of nylon 66 injection molded parts used in its mechanical part reaches 13kg. China FAW has established a processing line for nylon 66 intake manifold, and No.2 Automobile is also preparing for construction. With the technical progress of automobile industry, other automobile factories will adopt nylon 66 intake manifold one after another. At present, 80% of nylon 66 in China is still used to produce tire cord fabric, and there is huge room for improvement in the application of nylon 66 in automobiles in the future. Nylon alloying. By mixing other polymers, the water absorption of nylon can be improved, and the dimensional stability, low temperature brittleness, heat resistance and wear resistance of the product can be improved. For example, in the Wenzhou-Fuzhou high-speed railway system under construction, 70% of the special nylon 66 plastic fasteners are made of Huawei Plastic Engineering Company, a subsidiary of Pingmei Shenma Energy and Chemical Industry Group. This is the first time that domestic nylon 66 engineering plastics have been applied in key national high-speed railway infrastructure projects. This product has the characteristics of high strength, impact resistance and high rigidity, 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 retardant properties 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. , suitable for electronic equipment, mining machinery, textile machinery, etc.
