pet plastic raw materials, performance and use of description
Poly Class of plastic, it is important, including poly ethylene terephthalate (pet) and polyethylene terephthalate (pbt).
Development of Section III product or process technology features of the development trend of domestic and international technology analysis Chapter hose assembly of the domestic market, high pressure hose assembly Review Section Market Analysis and Forecast Section II hose total into a product yield analysis and prediction III high pressure hose assembly market demand analysis and forecast fourth quarter high-pressure hose assembly Consumption Analysis and Prediction of Section V of price trends in high-pressure hose assembly high pressure hose assembly VI Chapter VI of the import and export value of high-pressure hose assembly major health
pet material, substantial foreign exchange savings for the country. At present, China is still not pet manufacturers to produce plug-in-class flame retardant materials enhance the pet is generally limited to producing low-end of the lamp expected, but the production of material heat lamp can not reach some high level of heat resistance, high precision product size. Therefore, this type of high-heat high-precision products are now important to rely on imports, prices are 35,000 yuan per ton, while the independently developed by the research and development of new Kai Shing's pet fire-retardant materials enhance the performance indicators of the basic approach of imported materials, while the unit price only imported materials for the 3 / 4, has great potential market competition. Head
pet, highly symmetrical molecular structure, crystal orientation has a certain capacity, Guer high and into the nature of film. pet has a good optical performance and weather resistance, amorphous pet has good optical transparency. Another pet has an excellent wear resistance and dimensional stability of the friction and electrical insulation. pet bottles made with strength, good transparency, non-toxic, anti-permeability, light weight and high efficiency which has been widely used. pbt pet chains with similar structure, most of the same nature, only the main chain by two methylene into four, so a more compliant elements, processing and better performance.
(Pet) is the most common polyester, widely used to make fibers , films, bottles, plastic and many other areas, the pet of the synthesis, structure, properties and use of research and development has been widely. Poly 2,6-ethylene glycol ester of a naphthalate (pen) is a new pet of the same line separated polymer, such as pen on the water vapor barrier is the pet of 3-4 times, as the packaging material can greatly improve product shelf-life. Naphthalene molecules in the introduction of improved degree of aromatic molecules, making pen more than pet show more good heat resistance. pen the melting point of 265 ℃, the glass
type of plastic Poly important uses are:
thin film sheet: the types of food, medicines, non-toxic sterile packaging materials; textiles, precision instruments, electrical components, high-grade packaging materials; audio, video, film, computer discs, photographic film and other metal coating and the substrate; electrical insulation materials, capacitor film, flexible printed circuit board and membrane switch and other electronics and mechanical fields.
High temperature, it can only withstand temperatures of about 60 ~ c, but the recovery needs 80 ~ c bottle of water temperature, which is recycled beer bottles adverse effects. If the application of disposable plastic bottles, the cost will be relatively high. and. pet is a linear thermoplastic polyester, a typical high-crystalline polymers, is following the U.S. Food and Drug Control Council and the Government of Japan and other countries ban pvc for food and pharmaceutical packaging, the R & D out of a
package Bottle of use: its use by the first carbonated beverage to today's beer bottles, cooking oil bottles, condiment bottles, medicine bottles, cosmetic bottles.
Electronics: manufacture of connectors, coil winding tube, integrated shell, shell capacitor, transformer enclosure, TV accessories, tuner, switch, timer cover, auto fuses, motor bracket, and relays.
Auto Parts: If switchboard cover, ignition coils, valves, exhaust parts, distributor caps, measuring instruments Shell, Shell and other small motors can also use the pet a good painting, surface gloss and rigidity, manufacturing exterior car parts.
Machinery and equipment: manufacture of gears, cams, pump casing, pulley, motor frame and watch parts, but can be used as microwave oven baking, a variety of ceiling, outdoor billboards and model.
