PVC sheet is what material?

PVC sheet can be divided into soft PVC and rigid PVC. The hard PVC about market 2/3, soft PVC accounted for 1/3. Soft PVC is generally used for flooring, ceiling and leather surface, but because it contains softener soft PVC, crisp, not easy to save, so the range of use is limited. Hard PVC does not contain softeners, good flexibility, easy molding, not brittle, non-toxic no pollution, save for a long time, so the development and application of great value.
PVC sheet is based on PVC as a raw material, section plate honeycomb mesh structure. The PVC sheet is a vacuum membrane, the surface panel for packaging, has important application in building materials, packaging, medicine and many other industry. The building materials industry accounted for the largest proportion, followed by the packaging industry.
Hard PVC sheet with excellent corrosion resistance, insulation, and a certain mechanical strength; sulfuric acid tank can be made by two after processing; use the empty needle holder medicine, process frame; the public toilet water tank; template, decorative panels, exhaust pipe, processing equipment such as various special-shaped products, container liner that is the ideal chemical industry, building materials, decoration and other industries choice.
The hardness and mechanical properties of PVC sheet has high. And increase with the increase of molecular weight, but decreases with the increase of temperature. Mechanical properties of hard PVC board, soft PVC elasticity is a bit poor, but the elongation at break of higher. The friction of PVC plate in general, static friction coefficient is 0.4-0.5, the dynamic friction factor is 0.23. Thermal stability of PVC plate is very poor, 140 C began to decompose, the melting temperature of 160 DEG C. PVC linear expansion coefficient is small, is flame resistant, oxidation index is higher than 45. The PVC board is a kind of polymer better electrical performance, but because of their more polar, electrical insulation properties than PP plate and PE plate.
