So many commercial PP material is added 1-4% ethylene random copolymer or a higher ratio of clamp-stage ethylene content copolymer. Copolymer PP material has a lower heat distortion temperature (100 ℃), low transparency, low gloss, low rigidity PP plastic board manufacturers, but have a stronger impact strength. MFR PP turnover ranges from 1 to 40. Low MFR PP material better impact properties but extend lower strength. MFR for the same material, copolymer-based homopolymer type intensity ratio is higher. Since the crystal, PP contraction rate is very high PP plastic plate price, generally 1.8 to 2.5%. And uniform shrinkage direction than PE-HD material is much better. 30% of glass additive can make the shrinkage rate to 0.7%. PP foam board PP foam use applications and markets a wide range of uses, from small to large cup to the hull are applied. Foamed PP using its excellent heat resistance, hygiene, heat resistance and good environmental effects, it can play an important role in the field of packaging, automotive and building.
