Colored Polypropylene Sheet

Product introduction of the colored polypropylene sheet

The colored polypropylene sheet has lower thermal distortion temperature (100 C), low transparency, low gloss and low rigidity, but has stronger impact strength. The strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150 C. Because of its high crystallinity, the surface stiffness and scratch resistance of this material are very good. There is no environmental stress cracking in PP. Usually, PP is modified by adding glass fiber, metal additive or thermoplastic rubber. The MFR of PP ranges from 1 to 40. Low MFR P P material has better impact resistance but lower ductility. For the same MFR material, the strength of copolymer type is higher than that of homopolymer type. As a result of crystallization, the shrinkage of PP is quite high, generally 1.8-2.5%. And the directional uniformity of shrinkage rate is much better than that of PE-HD and other materials. The shrinkage can be reduced to 0.7% by adding 30% glass additive. Homopolymer and copolymer PP materials have excellent hygroscopicity, acid-base corrosion resistance and solubility resistance. However, it has no resistance to aromatic hydrocarbons (such as benzene) and chlorinated hydrocarbons (carbon tetrachloride) solvents. PP is not as antioxidant as PE at high temperature.
