Is UHMW engineering plastic or general-purpose plastic?

The meaning of engineering plastics

Engineering plastics can be used as engineering materials and plastics to replace metal manufacturing cnc machine parts. Engineering plastics have excellent comprehensive functions, high rigidity, small creep, high mechanical strength, good heat resistance, good electrical insulation, can be used for a long time in harsh chemical and physical environments, and can replace metals as engineering structure materials. , But the price is more expensive and the output value is smaller. Engineering plastics can be divided into general engineering plastics and special engineering plastics. The former main varieties include polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester five general machining plastics; the latter mainly refers to engineering plastics with heat resistance above 150 ℃, the main varieties are polyimide , Polyphenylene sulfide, polysulfones, aromatic polyamides, polyarylate, polyphenylene ester, polyaryl ether ketone, liquid crystal polymer and fluororesin, etc.

The meaning of general plastics

 Some plastic varieties with large output value, low price, wide application and wide influence are used to be called general-purpose plastics. Its connotation often changes with time and the development of science and technology. Important general-purpose plastics include polyethylene, polypropylene, polyvinyl chloride, polystyrene and other varieties.
General plastics mainly include polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS (acrylic acid-butadiene-styrene), polymethyl methacrylate and amino plastics, etc., whose output value accounts for More than 90%, so it is also called bulk plastic varieties.
It can be seen that machining UHMWPE can definitely be an engineering plastic, and once in the world and all countries have the ability to produce this product, most domestic products can only produce 2 million to 3 million molecular weight products. , Japan and other countries monopolize, and now only a few manufacturers can produce, Anyang Chaogao Industrial Technology Co., Ltd. is one of them. It can produce products with molecular weights between 5 million and 9 million. These products are mostly used in military and outer space.
