5, PP plate contraction rate is very high. Since PP plates are semi-crystalline materials plastic plate, shrinkage is generally 1.8 to 2.5%. And shrinkage direction uniformity than PE-HD material is much better. 6, with excellent resistance to moisture absorption, resistance to acid corrosion, anti-solubility. High magnification PP foam sheet by Chinese micro match the new materials developed and patented production (5-40 times the supercritical carbon dioxide foam). PP foam board performance (1) excellent heat resistance. PS foam is used at 80 ℃ plastic crates, PE foam capability only 70-80 ℃ ppr plastic sheeting, and foamed PP capability 120 ℃. PP foam is placed 22h at 120 ℃, dimensional shrinkage less than 2%, under the same conditions PE foam shrinkage is about 40%. Thus, the foamed PP can be used to use temperature exceeds 100 ℃ occasions. ppr plastic plates, plastic Wei Zhen (certified), Anshun plastic sheeting provided by Foshan Plastics Co., Ltd. Wei Zhen. Foshan Plastics Co., Ltd. Wei Zhen (cxsy2009.1688.com/) Guangdong Foshan, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
