Polyethylene terephthalate is the most important variety of thermoplastic polyester, English name Polyethylene terephthalate referred to as PET, commonly known as polyester resin.
What’s the Polyethylene terephthalate material?
Polyethylene terephthalate is the most important variety of thermoplastic polyester, English name Polyethylene terephthalate referred to as PET or PEIT (hereinafter referred to as PET), commonly known as polyester resin. The molar mass of the repeating unit is 192 g/mol. It is a polycondensate of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester.
PET is divided into fiber-grade polyester chips and non-fiber-grade polyester chips. ①Fiber-grade polyester is used to manufacture polyester staple fibers and polyester filaments, and is the raw material for polyester fiber enterprises to process fibers and related products. Polyester is the most productive variety of chemical fibers. ②Non-fiber polyester is also used for bottles, films, etc., and is widely used in the packaging industry, electronic appliances, medical and health, construction, automobiles and other fields. Among them, packaging is the largest non-fiber application market for polyester, and it is also the fastest growing PET market. fast field.
The Application of the Polyethylene Terephthalate (PET)
Films and sheets: all kinds of food, medicine, non-toxic and sterile packaging materials; high-grade packaging materials for textiles, precision instruments, and electrical components; Substrates; electrical insulating materials, capacitor films, flexible printed circuit boards and membrane switches and other electronic and mechanical fields.
Application of packaging bottle: Its application has been developed from the original carbonated beverage to beer bottles, edible oil bottles, condiment bottles, medicine bottles, cosmetic bottles, etc.
Electronic appliances: manufacture of connectors, coil bobbins, integrated circuit housings, capacitor housings, transformer housings, TV accessories, tuners, switches, timer housings, automatic fuses, motor brackets and relays, etc.
Auto parts: such as switchboard covers, ignition coils, various valves, exhaust parts, distributor covers, measuring instrument covers, small motor covers, etc., and the excellent paintability, surface gloss and rigidity of PET can also be used to manufacture automobiles exterior parts.
Mechanical Equipment: Manufacture of gears, cams, pump housings, pulleys, motor frames and clock parts, also can be used as microwave oven baking trays, various ceilings, outdoor billboards and models, etc.
