polypropylene PP Building chemistry use

Polypropylene for maskPolypropylene is a polymer formed by the addition of propylene. White waxy material, transparent and light in appearance. The density is 0.89 ~ 0.91g/cm3, flammable, melting point 165℃, softening at 155℃ or so, the operating temperature range is -30 ~ 140℃. Under 80℃ can withstand Acid, alkali, salt solution and a variety of organic solvents, can be decomposed under high temperature and oxidation. Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, cars, bicycles, parts, transport pipes, chemical containers and other production, also used in food, medicine packaging.

Usage of PolypropyleneMainly used for automotive, electrical parts, various containers, furniture, packaging materials and medical equipment; Film accounts for 8% ~ 15%, polypropylene fiber (polypropylene fiber) accounts for 8% ~ 10%; The pipes and plates used in building, etc., account for 10% ~ 15%, the others for 10% ~ 12%. At present, 40% ~ 45% of the products are used for weaving in China, followed by about 40% for film and injection products. Polypropylene and other accounts for 10% to 20%.Polypropylene for machinery and automotive partsPolypropylene has good mechanical properties, can be directly manufactured or modified after the manufacture of a variety of mechanical equipment parts, such as manufacturing industrial pipelines, agricultural water pipes, motor fans, infrastructure templates.The modified polypropylene can be molded into bumper, friction-proof strip, automobile steering wheel, instrument panel and interior decoration, which can greatly reduce the body weight and save energy.Polypropylene for Electronic and electrical industrial devicesModified polypropylene can be used to make the insulation shell of household appliances and the liner of washing machine.In the preparation of barrier film, the traditional membrane production process can be used for production, the process is relatively simple, the production cost is low.Polypropylene for construction industryPolypropylene fiber is the lightest of all the chemical fiber, its density is (0.90 ~ 0.92 g/cm3), high strength, good toughness, good resistance to chemical and microbial resistance and low price advantage, using glass fiber reinforced modified or rubber, SBS modification of polypropylene foam is widely used to make construction project template of polypropylene can be used in the production of decorative materials. When the earthquake occurred, the failure form of polypropylene fiber ceramsite concrete was plastic failure and there was no fragmentation. Polypropylene fiber ceramsite concrete is safer than plain ceramsite concrete.Polypropylene for Agriculture, fishing and food industryPolypropylene can be used to make greenhouse gaskets, plastic film, culture bottles, farm tools, fishing nets, etc., food containers, food bags, beverage packaging bottles, etc. It was reactively blended with waste PET (polyethylene terephthalate) to produce multi-functional waste PET, and the in-situ fiber - forming composites were made from the multi-functional waste PET and polypropylene. Polypropylene for Textile and printing industriesPolypropylene is the raw material of synthetic fiber, polypropylene fiber is widely used in the production of lightweight and beautiful durable textile supplies, the use of polypropylene material printing out a particularly bright, bright, beautiful.Other industriesIn the chemical industry, polypropylene can be used to prepare a variety of corrosion resistant pipelines, storage tanks, valves, packing tower of the special packing, filter cloth, corrosion resistant pumps and corrosion resistant containers lining; In medicine can be used to make medical equipment; Polypropylene can also be developed and applied in the field of energy through grafting, composite and blending processes.
