What is engineering plastic?
Engineering plastics generally refer to plastics that can withstand a certain external force, have good mechanical properties, high and low temperature resistance, and have good dimensional stability. They can be used as engineering structures, such as polyamide and polysulfone.
In engineering plastics, it is divided into two categories: general engineering plastics and special engineering plastics. Engineering plastics can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in electrical and electronic, automotive, construction, office equipment, machinery, aerospace and other industries. Substituting plastic for steel and plastic for wood has become an international trend.
General engineering plastics include: polyamide, polyoxymethylene, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methylpentene polymer, vinyl alcohol copolymer, etc.
Special engineering plastics are divided into cross-linked and non-cross-linked types. Cross-linked types are: polyamino bismaleamide, polytriazine, cross-linked polyimide, heat-resistant epoxy resin and so on. Non-crosslinked types are: polysulfone, polyethersulfone, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK) and so on.
