Nylon, as the largest and most important variety in engineering plastics, has strong vitality, mainly due to its high performance after modification, followed by automotive, electrical, telecommunications, electronics, machinery and other industries that are increasingly demanding high-performance products. The more intense, the rapid development of related industries has promoted the progress of high-performance engineering plastics. The future development trend of modified nylon is as follows.

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 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 realize the high performance of nylon, and it is also the main means for manufacturing nylon special materials and improving the performance of nylon. 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 wear resistance are improved. As a result, it is suitable for different types of applications.

The manufacturing technology and application of 3-nanometer nylon will be rapidly developed. The advantage of nano-nylon is that its thermal properties, mechanical properties, flame retardancy, and barrier properties are higher than that of pure nylon, and the manufacturing cost is comparable to that of back-pass nylon. Therefore, it is very competitive. The

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

5 Antistatic, conductive nylon and magnetic nylon will become the preferred materials 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 nylons. The

7 The application of comprehensive technology, the refinement of products is the driving force for the development of its industry
