PVC materials in the actual use of often added stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives. With non-flammability, high strength, weather resistance and excellent geometric stability. PVC has a strong resistance to oxidants, reducing agents and strong acids. However, it can be strongly oxidized acid such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply with aromatic hydrocarbons, chlorinated hydrocarbons in contact with the occasion.
