Because polyamide has non-toxicity, light weight, excellent mechanical strength, abrasion resistance and good corrosion resistance, it is widely used in the manufacture of bearings, gears, etc. in the machinery, chemical, instrument, automobile and other industries instead of copper and other metals. Pump blades and other parts. In terms of product development, high-performance nylon PA6, PA66, toughened nylon, nano-nylon, and halogen-free flame-retardant nylon are the main directions; in terms of application, significant progress has been made in the development of automotive components and electrical components, such as automotive air intake High-flow modified nylon for pipe has been commercialized. The plasticization of this complex structure component is of great significance in application, and it is more important to extend the life of the component and promote the development of engineering plastic processing technology.

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

2. Nylon alloying will become the mainstream of the development of modified engineering plastics. Nylon alloying is an important way to achieve the high performance of nylon, and it is also the main means of manufacturing nylon special materials and improving nylon performance. By blending other polymers, the water absorption of nylon is improved, the dimensional stability of the product is improved, and the low temperature brittleness, heat resistance and abrasion resistance are improved. Therefore, it is suitable for different requirements of vehicle types.

3. Nano-nylon manufacturing technology and applications will develop rapidly. The advantage of nano-nylon is that its thermal properties, mechanical properties, flame retardancy and barrier properties are higher than those of pure nylon, and the manufacturing cost is comparable to ordinary nylon. Therefore, it has great competitiveness.

4. Flame retardant nylon used in electronics, electrical, and electrical appliances is increasing day by day, and green flame retardant nylon is receiving more and more attention from the market.

5. Antistatic, conductive nylon and magnetic nylon will become the materials of choice for electronic equipment, mining machinery, and textile machinery.

6. The research and application of processing aids will promote the functionalization and high performance of modified nylon.

7. The application of comprehensive technology and the refinement of products are the driving force for the development of its industry.
