Jiangmen engineering plastics refer to industrial plastics used for industrial parts or shell materials. They are plastics with excellent strength, impact resistance, heat resistance, hardness and aging resistance. Engineering plastics refer to the plastics that do structural data in engineering. These plastics generally have high mechanical strength, or have outstanding functions such as high temperature resistance, corrosion resistance and wear resistance, so they can replace metal to do some mechanical parts. There are many functions and applications of thermoplastic engineering plastics, such as polyamide, polytetrafluoroethylene, ABS plastics, polyformaldehyde, polycarbonate, etc.

Engineering plastics are a kind of high-performance polymer materials which can be used as structural data, accept mechanical stress in a wide temperature range, and can be used in harsh chemical and physical environment. Generally, it refers to the plastic which can accept certain external force, has outstanding mechanical function and dimensional stability, can still adhere to its function under high and low temperature, and can be used as engineering structural parts. Such as ABS, nylon, poly alum, etc.

Compared with general plastics, engineering plastics can meet higher requirements in mechanical function, durability, corrosion resistance and heat resistance, and can be processed more conveniently and can replace metal data. Engineering plastics are widely used in electrical and electronic, car, building, office equipment, machinery, aerospace and other occupations. Replacing steel with plastic and wood with plastic has become a popular trend in the world. Engineering plastics has become a rapidly increasing category in the world plastics industry. Its development not only supports the national pillar industry and modern high-tech industry, but also promotes the transformation of traditional industries and the adjustment of product structure.

In engineering plastics, additional additives are often required because of some functional requirements. In the process of processing, functional masterbatch processing method will be selected. The dispersibility and matrix compatibility of masterbatch are more suitable for the increase of plastics. Due to the rapid development of engineering plastics, the development of additives and functional masterbatch is also promoted.
