Polypropylene 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.
