In actual use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives. It is non-flammable, High strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids.
