PET plastics are the abbreviations of Polyethylene terephthalate, mainly including PET and PBT. Polyethylene terephthalate, also commonly known as polyester resin. In recent years, the demand for flame-retardant engineering plastics engineering plastics is increasing, as the cost of material increases greatly, the low price PET is paid more attention to compared with PBT. In addition, the PET alloy can be reduced or not added with inorganic filler, thus reducing the coefficient of thermal expansion, improving surface appearance and increasing processing fluidity.
Areas of application:
Thin film sheet
All kinds of food, medicine, aseptic packaging materials; textiles, precision instruments, high-grade packaging materials of electrical components; audio tape, video tape, film, computer floppy disk, metal coating and photographic film base materials; Electrical insulation materials, capacitor film, flexible printed circuit board and film switch and other fields of electronics and machinery.
Its application has been developed from carbonated gas beverage to beer bottle, edible oil bottle, seasoning bottle, medicine bottle, cosmetics bottle and so on.
Manufacturing connectors, coils winding tubes, integrated circuit shells, capacitor case, transformers case, TV accessories, tuners, switches, timer casings, automatic fuses, motor brackets and relays, etc.
Such as switchgear hood, ignition coil, various valves, exhaust parts, distributor cover, metering apparatus housing, small motor housing, etc., PET can also be used for excellent coating, surface gloss and rigidity to manufacture automotive exterior parts.
PET can be used to manufacture gears, cams, pump housing, pulleys, motor frames and clock parts, as well as microwave ovens, various roofs, outdoor billboards and models.
PET plastics can be molded, extruded, blown, coated, bonded, machined, electroplated, vacuum plated, and printed.
When PET is used in plastic sheets, bottles, chemical fibers and other fields, because of its chemical characteristics, it needs to be tackified and toughened before the final products are produced.
