What are the 5 major engineering plastics in the world? What's the use of him?
(local name: PA, nylon) because of its unique low weight, high tensile strength, wear resistance, self lubrication and good performance, excellent impact toughness, and with the rigid flexible and win people's attention, and it has the advantages of easy processing, high efficiency, light weight (only metal 1/7), can be processed into various products to replace metal, widely used in automotive and transportation industry. Typical products are pump impeller, fan blades, bearings, bushings, valve seats, instrument panels, automotive electrical instruments, cold and hot air valve parts, each car consumes about 3.6~4 kg of nylon products. Polyamides account for the largest proportion of consumption in the automotive industry, followed by electronic and electrical industries.
POM (POM) is a kind of engineering plastics with excellent properties. It is called "taking steel" or "super steel" in other countries. POM has a similar metal hardness, strength and steel, the temperature and humidity in a wide range of fatigue resistance and self lubrication, good good, and flexible, in addition it has good chemical resistance. POM to less than many other engineering plastics cost, are replacing some of the traditional metal is occupied by the market, such as alternative production of zinc, brass, aluminum and steel in many parts, since its inception, POM has been widely used in electronic and electrical, mechanical, instrumentation, automotive, building materials, light industry, agriculture and other fields. In many new areas of application, such as medical technology, sports equipment and so on, POM also showed a good growth trend.
(PC) not only has the strength similar to that of non-ferrous metals, but also has both ductility and toughness. Its impact strength is extremely high. It can not be damaged by hammering with a hammer and can withstand the explosion of a TV screen. The transparency of the polycarbonate is excellent and can be applied to any color. Because of the excellent properties of polycarbonate, has been widely used in all kinds of safety lamp, signal lamp, gymnasium, stadium lighting glass, a transparent protective plate, high-rise building glass, car mirror, windshield plate, glass cockpit, motorcycle safety helmet. The most expensive markets are computers, office equipment, cars, glass and sheets, and CD and DVD discs are among the most promising.
Domestic general is polycarbonate, POM, polyamide, thermoplastic polyester, modified polyphenylene oxide and other five major engineering plastics..
