PVC skin board is a very smooth surface. , high hardness, not easy to produce scratched sheet, often used in cabinets, sofas, tables and other furniture. We all know that PVC crust boards have good waterproof, moisture-proof, anti-mite, thermal insulation and other properties. There are many ways to process them, but the processing performance is better than wood. PVC crust board is the main raw material is PVC resin, PVC resin is a white or light yellow powder, which has high hardness and mechanical properties. It increases as the molecular weight increases, but decreases as the temperature increases. The PVC crust board has good mechanical properties and high elasticity. However, the elongation at break is as high as about 400%, and the friction of the PVC crust board is general. In terms of thermal performance, PVC skinboard has poor heat resistance stability, PVC has a small coefficient of linear expansion, is flame retardant, and has an oxidation index of more than forty-five. In terms of electrical properties, PVC crust board is a polymer with better electrical properties. In terms of environmental performance, PVC crust board can withstand most inorganic acids, alkalis, salts, and most organic solvents, so it has good anti-corrosion properties.
