High Quality Plastic Particles for GPPS Industry/Plastic Products
Polypropylenes is a polymer of propylenes by addition polymerization. It is white waxy material, transparent and light in appearance. Chemical formula is (C3H6) N, density 0.89 ~ 0.91g/cm3, flammable, melting point 189oC, softening at 155oC or so, the use of temperature range of -30 ~ 140oC. Under 80oC, it can resist the corrosion of acid, alkali, salt liquid and various organic solvents, and can decompose under the action of high temperature and oxidation. PolypropyleneS is widely used in the production of clothing, blankets and other fiber products, medical instruments, automobiles, bicycles, parts, pipelines, chemical containers, and also used in food and drug packaging.
Product Feature:(1) The relative density is small, only 0.89-0.91, which is one of the lightest varieties in plastics.
(2)good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding processing performance is good.
(3) It has high heat resistance and the continuous use temperature can reach 110-120 °C.
(4)good chemical properties, almost no water absorption, and does not react with most chemicals.
(5)the texture is pure, non-toxic.
(6) electrical insulation is good.
