pp is a semi crystalline material. it is harder than pe and hasa higher melting point. because homopolymer type pp is very brittlewhen the temperature is above 0c, many commercial pp materials areirregular copolymers with 1-4% ethylene or clamp copolymers withhigher ethylene content. the copolymer type pp material has lowerheat distortion temperature (100c), low transparency, low gloss,low rigidity, but stronger impact strength. the strength of ppincreases with the increase of ethylene content. the vicatsoftening temperature of pp is 150c. due to its high crystallinity,this material has good surface stiffness and scratch resistance.china plastics online plastics encyclopediahttps://baike.21cp.com

there is no environmental stress cracking in pp. in general, ppis modified by adding glass fiber, metal additive or thermoplasticrubber. the mfr of pp ranged from 1 to 40. pp with low mfr hasbetter impact resistance but lower ductility. for the same mfrmaterial, the strength of copolymer type is higher than that ofhomopolymer type. due to crystallization, the shrinkage of pp isquite high, generally 1.8 ~ 2.5%. and the directional uniformity ofshrinkage is much better than that of pe-hd and other materials.adding 30% glass additive can reduce the shrinkage to 0.7%. bothhomopolymer type and copolymer type pp materials have excellentmoisture absorption resistance, acid-base corrosion resistance andsolubility resistance. however, it has no resistance to aromatic(such as benzene) solvents and chlorinated hydrocarbon solvents.[2]
