| Product description Product specification: Thickness: 1-15mm, the maximum width is 1500mm Thickness: 15-30mm, maximum width 1300mm Thickness: 30-60mm, maximum width 1100mm Polypropylene (PP) board, (PP pure board, modified PP board, reinforced PP board, PP electrode) Pure PP board: low density, easy to weld and process, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless, is one of the most environmentally friendly engineering plastics. The main colors are white, computer color, other colors can also be customized according to customer requirements. Maximum width of product: 1500mm Product length: 100-10000mm recommended specification: 1300 × 2000mm 1000 × 2000 Modified PP board (calcium plastic board): good dimensional stability, low price, rigidity, heat resistance, etc. are better than pure PP. The color is generally green, white and beige. It is mainly used to make water tank and three-phase separator. Product thickness: 2-30mm Recommended specification: 1000 × 2000mm Product performance Glass fiber reinforced PP board (FRPP board): after being reinforced by 20% glass fiber, in addition to maintaining the original excellent performance, the strength and rigidity of FRPP board are doubled compared with PP, and it has good heat resistance, low temperature impact resistance, corrosion resistance, arc resistance and low shrinkage. It is especially suitable for chemical fiber, chlor alkali, petroleum, dye, pesticide, food, medicine, light industry, metallurgy, sewage treatment and other fields. Because homopolymer type PP is very brittle when the temperature is higher than 0 ℃, many commercial PP materials are irregular copolymers with 1 ~ 4% ethylene or clamp block copolymers with higher ethylene content. The copolymer PP material has lower thermal distortion temperature (100 ℃), low transparency, low gloss and low rigidity, but it has stronger impact strength. The strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP was 150 ℃. Due to its high crystallinity, the material has good surface stiffness and scratch resistance. There is no environmental stress cracking in PP. Usually, PP is modified by adding glass fiber, metal additive or thermoplastic rubber. The MFR of PP ranged from 1 to 40. PP with low MFR has better impact resistance but lower tensile strength. For the same MFR material, the strength of copolymer type is higher than that of homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8 ~ 2.5%. And the directional uniformity of shrinkage is much better than that of PE-HD. The shrinkage can be reduced to 0.7% by adding 30% glass additive. Both homopolymer and copolymer PP materials have excellent hygroscopicity, acid-base corrosion resistance and solubility resistance. However, it has no resistance to aromatic solvents (such as benzene) and chlorinated hydrocarbons (carbon tetrachloride) solvents. PP also does not have antioxidant activity at high temperature like PE. Mainly used in industrial construction, decoration and other fields |
