That is, the PVC material that meets the requirements of international environmental protection standards has no pollution or less pollution. PVC is polyvinyl chloride, or PVC (Polyvinylchloride) for short. It is an initiator of vinyl chloride monomer (VCM) in peroxides, azo compounds, etc .; Made of polymers.

Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. Its material is an amorphous material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use.

Has non-flammability, high strength, weather resistance and excellent geometric stability. PVC is very resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
