Polypropylene is a polymer formed by the reaction of propylene by adding polymerization. It is a white waxy material with a transparent and light appearance. The density is 0.89 ~ 0.91g / cm3, flammable, the melting point is 189 ° C, softening around 155 ° C, and the use temperature range is -30 ~ 140 ° C. Below 80 °C, it can resist the corrosion of acids, alkalis, salines and a variety of organic solvents, and can decompose at high temperatures and oxidation
Polypropylene is a strong, flexible artificial material that is used to make things such as rope, clothing,carpet,medical apparatus,automobile,bicycle,chemical containers and pipes production.And also for food and drug packing.
