PET plastic English Polyethylene terephthalate abbreviation, referred to as PET or PETP. Chinese meaning is: Poly terephthalate plastic, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT. Polyethylene terephthalate and commonly known as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, together with PBT collectively referred to as thermoplastic polyester, or saturated polyester. As one of the five major engineering plastics, PET can be applied in what areas?
First, PET for the industry
Fiberglass Reinforced PET is suitable for use in the electrical, electronic and automotive industries for a variety of bobbins, transformers, televisions, recorder components and enclosures, automotive lampholders, lampshades, white hot lampholders, relays, selenium rectifiers and more. PET engineering plastics currently several areas of consumption ratio: electrical and electronic 26%, 22% of vehicles, machinery 19%, appliances 10%, 10% of consumer goods, other 13%. At present, the total consumption of PET engineering plastics is not large, accounting for only 1.6% of the total amount of PET.
Second, PET all aspects of the current application
1. Film sheet: all kinds of food, medicine, non-toxic and aseptic packaging materials; textiles, precision instruments, components of the high-end packaging materials; tapes, video tapes, films, floppy disks, metal coating and photographic film And other electronic materials; electric insulating materials, capacitor films, flexible printed circuit boards and membrane switches and other electronic fields and machinery.
2. Bottle application: Its application has been developed from the original carbonated drinks to the current beer bottles, edible oil bottles, condiment bottles, medicine bottles, cosmetic bottles and so on.
3. Electronics: Manufacturing connectors, coil bobbins, integrated circuit housings, capacitor housings, transformer housings, TV accessories, tuners, switches, timer housings, automatic fuses, motor brackets and relays.
4. Auto parts: such as the switchboard cover, ignition coil, various valves, exhaust parts, distributor cover, measuring instrument cover, small motor cover, etc., can also use PET excellent coating, surface gloss and rigidity, Manufacture of automotive exterior parts.
5.Machinery and equipment: manufacturing gears, cams, pump casings, pulleys, motor frames and watch parts can also be used as microwave ovens bakeware, all kinds of ceilings, outdoor billboards and models.
6.PET plastic molding can be injection molding, extrusion, blow molding, coating, bonding, machining, electroplating, vacuum metallization, printing.
