Unlike general-purpose plastics, engineering plastics are plastic materials that can be used as engineering materials and replace metal to manufacture machine parts. Compared with conventional general-purpose plastics, it can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and has stronger plasticity. It can also be used for a long time in harsh chemical and physical environments. It can be used in place of some metal materials.
At present, engineering plastics have long been widely used in electrical and electronic, automobile manufacturing, construction industry, machinery and equipment manufacturing and other industries. It has become an industry development trend to replace steel with plastic and replace wood with plastic. Therefore, although engineering plastics have high cost and low output, they have become the fastest growing field in the world's plastics industry. Its development not only plays an important supporting role for the national pillar industry and modern high-tech industry, but also promotes the transformation of traditional industries and the adjustment of product structure.
