Engineering plastics can be used as engineering materials and plastics that replace metal parts for machine parts. Engineering plastics have excellent comprehensive performance, high rigidity, small creep, high mechanical strength, good heat resistance, good electrical insulation, long-term use in harsh chemical and physical environments, and can be used as an alternative structural material for metal.
Engineering plastics can be divided into general engineering plastics and special engineering plastics. The former main varieties are polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester five general engineering plastics; the latter mainly refers to engineering plastics with heat resistance up to 150 ° C, the main varieties are polyimide , polyphenylene sulfide, polysulfone, aromatic polyamide, polyarylate, polyphenyl ester, polyaryl ether ketone, liquid crystal polymer and fluororesin.
The performance characteristics of engineering plastics are mainly:
(1) Compared with general-purpose plastics, it has excellent heat resistance and cold resistance, and has excellent mechanical properties in a wide temperature range, and is suitable for use as a structural material;
(2) Good corrosion resistance, less environmental impact, and good durability;
(3) Compared with metal materials, it is easy to process, has high production efficiency, and can simplify procedures and save costs;
(4) Good dimensional stability and electrical insulation;
(5) Light weight, high specific strength, and outstanding friction and wear resistance.
We mainly produce Teflon (polytetrafluoroethylene), polyurethane and injection molded parts from various of plastic materials..
Compared with general-purpose 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. It has become an international trend to replace steel and plastic. Engineering plastics has become the fastest growing field in the plastics industry in the world. Its development not only supports the national pillar industry and modern high-tech industries, but also promotes the transformation of traditional industries and product structure.
Engineering plastics are increasingly used in automobiles, mainly for bumpers, fuel tanks, instrument panels, body panels, doors, lampshades, fuel pipes, radiators, and engine-related components.
In engineering, engineering plastics can be used for mechanical parts such as bearings, gears, screw nuts, seals and other mechanical parts such as housings, covers, handwheels, handles, fasteners and pipe joints.
In electronic appliances, engineering plastics can be used for wire and cable coating, printed circuit boards, insulating films and other insulating materials and electrical equipment structural parts.
In household appliances, engineering plastics can be used in refrigerators, washing machines, air conditioners, televisions, electric fans, vacuum cleaners, electric irons, microwave ovens, rice cookers, radios, combination audio equipment and lighting fixtures.
In the chemical industry, engineering plastics can be used in chemical equipment such as heat exchangers, chemical equipment linings, and chemical pipelines such as pipes and pipe fittings, valves, pumps, etc.
