Generally refers to the ability to withstand a certain external force, with good mechanical properties and resistance to high and low temperature performance, dimensional stability is good, can be used as engineering structure of plastics, such as polyamide, Polysulfone and so on. In Engineering Plastics, it is divided into general Engineering Plastics and special Engineering Plastics two major categories. Engineering Plastics in mechanical properties, durability, corrosion resistance, heat resistance and other aspects can achieve higher requirements, and processing more convenient and can replace metal materials. Engineering Plastics are widely used in electronic, electrical, automotive, construction, office equipment, machinery, aerospace and other industries, to plastic generation of steel, to the plastic generation of wood has become an international fashion trend.
General Engineering Plastics include: polyamide, POM, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methyl isoprene polymers, vinyl alcohol copolymer.
Special Engineering Plastics and cross-linked type of non-crosslinking type of points. Cross-linked types are: Poly-imide amide, poly-Triazine, cross-linked polyimide, heat-resistant epoxy tree fingers. Non-cross-linked are: Polysulfone, PES, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK) and so on.
