Bulk PVC Plastic Rigid Sheet is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, medicine, decoration and water treatment and other fields. The pp board degree can reach 100 degrees. PP sheet application range Acid and alkali resistant equipment, environmental protection equipment, waste water, waste gas discharge equipment, scrubbers, clean rooms, semiconductor factories and related industries equipment, is also the material of choice for manufacturing plastic water tanks, of which PP thick sheets are widely used in Stamping board, punching mattress board, etc.
Chemical and physical properties of Bulk PVC Plastic Rigid Sheet: PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle at temperatures above 0°C, many commercial PP materials are random copolymers with 1 to 4% ethylene added or pinched copolymers with higher ethylene content. The copolymer-type PP material has a lower thermal distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has a stronger impact strength. The strength of PP increases with increasing ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high degree of crystallinity, this material has good surface stiffness and scratch resistance properties. PP does not have environmental stress cracking problems.
All in all, both homopolymer type and copolymer type Bulk PVC Plastic Rigid Sheet have excellent moisture absorption resistance, acid and alkali corrosion resistance, and dissolution resistance.
