Strong strength, wear-resisting, waterproof, corrosion resistant, thermal insulation, insulation, etc. And plastic sheet has the weight light cost low, easy to process, can be recycled

The strength of PP increases with the increase of ethylene content. PP vicat softening temperature is 150 ℃. Due to the high degree of crystallinity, the surface stiffness and anti-scratch characteristics of this material are very good. There is no environmental stress cracking problem. The PP is usually modified with glass fiber, metal additives or thermoplastic rubber. The flow rate of PP is in the range of 1 ~ 40. PP materials with low MFR have good anti-impact properties but low tensile strength. For the same MFR material, the copolymer type is higher than the homopolymer type. Because of crystallization, the shrinkage rate of PP is quite high, generally 1.8 ~ 2.5%. The direction of shrinkage is much better than that of PE - HD. Adding 30% of glass additives can reduce the systolic rate to 0.7%. Both polymer and copolymer PP materials have excellent anti-hygroscopic properties, corrosion resistance and solubility. However, it has no resistance to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents. PP is not as resistant to oxidation as PE.
