1.Product Description
Polypropylene
Polypropylene is a polymer formed by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89~0.91g/cm3, It is flammable, with a melting point of 189oC, softening at about 155oC, and the use temperature range is -30~140oC . It is resistant to corrosion by acids, alkalis, salt solutions and a variety of organic solvents below 80°C, and can be decomposed under high temperature and oxidation.
PP Features
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.
