That is, it meets the requirements of international environmental protection standards, and has no pollution or less pollution of PVC materials. PVC is polyvinyl chloride, English abbreviation PVC (Polyvinylchloride), is vinyl chloride monomer (vinylchloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat according to free radical polymerization mechanism polymerization formed polymer.
Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. Its material is an amorphous material. In practical use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives.
It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC is very resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
