Polypropylene PP Plastic Sheet 15mm Thick

Polypropylene PP sheet is a semi-crystalline material, it is harder than pe and has a higher melting point. PP board has low density, easy processing, superior chemical resistance, heat resistance and impact resistance, non-toxic and odorless, and is one of the engineering plastics most in line with environmental protection requirements.

Polypropylene PP plastic sheet 15mm thick is easy to weld and process, has excellent chemical resistance, heat resistance and impact resistance, non-toxic, and odorless. It is currently one of the most environmentally friendly engineering plastics. Performance; glass fiber reinforced PP board (FRPP board): After 20% is reinforced by glass fiber, in addition to maintaining the original excellent performance, the strength and rigidity are doubled compared to PP, and it has good heat resistance, low temperature Impact resistance, corrosion resistance and arc resistance, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.

Since homopolymer PP is very brittle when the temperature is higher than 0°C, many commercial PP materials are random copolymers with 1 to 4% ethylene or clamp copolymers with higher ethylene content. Copolymer PP material has lower thermal distortion temperature (100°C), low transparency, low gloss, 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. Due to the high crystallinity, the surface rigidity and scratch resistance of this material are very good. PP does not have the problem of environmental stress cracking. Usually, the PP is modified by adding glass fiber, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength.

For materials with the same MFR, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage rate is much better than that of PE-HD and other materials. Adding 30% of glass additives can reduce the shrinkage rate to 0.7%. Both homopolymer and copolymer PP materials have excellent moisture absorption, acid and alkali corrosion resistance, and solubility resistance. However, it has no resistance to aromatic hydrocarbon (such as benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. PP does not have oxidation resistance at high temperatures like PE.
