white lamp holder, relays, selenium rectifier. PET engineering plastics in the current application of the proportion of several areas: 26% of electrical and electronic, automotive 22%, 19% of machinery, appliances 10%, 10% of consumer goods, other 13%. At present the total consumption of PET engineering plastics is not large, only 1.6% of total PET. 1 film sheet: all kinds of food, pharmaceuticals, non-toxic sterile packaging materials; textiles, precision instruments, electrical components of high-grade packaging materials; tapes, video tapes, film, computer floppy, metal coating and photographic film , Electrical insulating materials, capacitor films, flexible printed circuit boards and membrane switches, and other electronic and mechanical fields. In this case,
2 bottle applications: the application has been from the initial development of carbonated beverages to the present beer bottles, edible oil bottles, condiment bottles, medicine bottles, cosmetic bottles. In this case,
3 electrical and electronic: manufacturing connectors, coil bobbin, integrated circuit casing, capacitor shell, transformer housing, TV accessories, tuner, switch, timer shell, automatic fuse, motor bracket and relays. In this case,
4 auto parts: such as the distribution plate cover, ignition coil, a variety of valves, exhaust parts, distributor cover, measuring instrument cover, small motor housing, etc., can also use PET excellent coating, surface gloss and rigidity, Exterior parts for automobiles. 5 Machinery and equipment: Manufacture of gears, cams, pump housings, pulleys, motor frame and watch parts, can also be used as microwave oven baking pan, a variety of ceiling, outdoor billboards and models. .
6 PET plastic molding process can be injection molding, extrusion, blow molding, coating, bonding, machining, plating, vacuum metallization, printing. In this case,
Common PET: common in mineral water bottles, carbonated beverage bottles. When the temperature reaches 70 ℃ easily deformed, and there is harmful to the material melt. 1 after 10 months of use of plastic products, may release carcinogenic DEHP. Such bottles can not be placed in the car sun, not wine, oil and other substances. In this case,
7, PS (polystyrene plastic) Polystyrene is a macromolecule chain, including styrene-based plastic
