Good Stability, Low Price, Rigidity, Heat Resistance
Apr 28, 2018

Polypropylene (PP) extruded sheet is a plastic sheet made of PP resin added to various functional auxiliaries by extrusion, calendering, cooling, cutting and other processes. The PP board is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle when the temperature of the PP is above 0° C., many commercial PP materials are random copolymers with 1 to 4% ethylene or higher ethylene content clamped segment copolymers. The copolymer PP material has a low heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has a stronger impact strength.

Modified PP board (calcium plastic board): good dimensional stability, low price, rigidity, heat resistance, etc. are somewhat higher than that of pure PP. The color is generally green, white, beige. Mainly used for water tanks, three-phase separator products.

Glass fiber reinforced PP board (FRPP board): After being reinforced by 20% of glass fiber, in addition to maintaining the original excellent performance, the strength and rigidity are double that of PP, and it has good heat resistance and low temperature impact. , anti-corrosion arc resistance, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.
