PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the PP temperature of the homopolymer type is very brittle when it is higher than 0 \u00b0 C, many commercial PP materials<\/a><\/strong> are random copolymers of 1 to 4% ethylene or a clamp copolymer of a higher ratio of ethylene. The copolymer type PP material has a low heat distortion temperature (100 \u00b0 C), low transparency, low gloss, low rigidity, but has a stronger impact strength. <\/p>

The strength of PP increases as the ethylene content increases. The Vicat softening temperature of PP is 150 \u00b0C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP. The PP is usually modified by adding glass fibers, metal additives or thermoplastic rubber.<\/p>

PP'nin ak\u0131\u015f h\u0131z\u0131, 1 ile 40 aras\u0131nda bir MFR'ye sahiptir. D\u00fc\u015f\u00fck MFR'ye sahip PP malzemeleri daha iyi darbe direncine sahipken, uzama oranlar\u0131 daha d\u00fc\u015f\u00fckt\u00fcr.

Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8 to 2.5%. And the direction uniformity of shrinkage is much better than materials such as PE-HD. <\/p>

The addition of 30% glass additive can reduce the shrinkage to 0.7%. Both the homopolymer type and the copolymer type PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it is not resistant to aromatic hydrocarbons (such as benzene) solvents, hydrogen chloride (carbon tetrachloride) solvents, and the like. <\/p>

PP does not have oxidation resistance at high temperatures like PE, and it is harmful to the human body.<\/p>
