PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the homopolymer PP is brittle at temperatures above 0C, many commercial PP materials are random copolymers with 1 to 4% ethylene or clamp copolymers of higher ethylene content. Copolymer PP materials have a low heat distortion temperature (100C), low transparency, low gloss, and low rigidity, but have stronger impact strength. The strength of PP increases with the ethylene content.


   The Vicat softening temperature of PP is 150C. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance.


    PP does not have the problem of environmental stress cracking. In general, PP is modified by adding glass fibers, metal additives, or thermoplastic rubber. PP flow rate MFR range is 1~40. PP materials with low MFR have better impact resistance but lower strength. For the same MFR material, the copolymer type has higher strength than the homopolymer type.


    Due to crystallization, PP shrinkage is quite high, typically 1.8 to 2.5%. And the uniformity of the shrinkage direction is much better than that of materials such as PE-HD. Adding 30% of the glass additive can reduce the shrinkage to 0.7%.


    Homopolymer and copolymer PP materials have excellent resistance to moisture absorption, acid and alkali corrosion, and resistance to dissolution. However, it is not resistant to aromatic hydrocarbons such as benzene solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, and the like.


    The use of PP material taps: quality and cheap, non-toxic and tasteless, environmental protection, water, product appearance, quality, with health, water, durability, practical and environmentally friendly features
