PVC environmental rating points ROHS, 6P, 15P, of which 15P is the most environmentally friendly, ROHS is low toxicity, in fact, she is inside the non-environmentally friendly things (all containing plasticizers), China's environmental requirements are only A minimum standard for the hazardous substances it contains,
I see a lot of online marked "green PVC" words of the product, but the search and found that PVC and this kind of thing is almost plastic, in fact, not environmentally friendly. I am very confused, that is, environmental protection is not environmentally friendly ah? Now how much of the PVC products on the market are really environmentally friendly?
Some of the toxic additives and plasticizers in the PVC may be seeped or vaporized; some of the additives may interfere with the biological endocrine (affecting reproductive function), some may increase the risk of carcinogenic; incinerated PVC waste will produce carcinogenic dioxin and pollute the atmosphere The In the manufacture, use and disposal, will produce a lot of dioxins, chloric acid, lead and other harmful substances; PVC material burning will occur when a lot of smoke, and produce harmful HCL gas; and most of the PVC material Contains Pb (lead), Cd (cadmium) and other (used as cable stabilizer) a variety of harmful heavy metals, will cause some harm to human health; incineration or burial, will cause soil and water pollution.
Hope you can be satisfied!
That is in line with international environmental standards, non-polluting or less pollution of PVC materials.
PVC is polyvinyl chloride, English referred to as PVC (Polyvinyl chloride), vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in the peroxide, azo compounds and other initiator; or in the light, heat by free radical polymerization Reaction mechanism polymerization of the polymer. Vinyl chloride homopolymer and vinyl chloride copolymer collectively referred to as vinyl chloride resin. The material is a non-crystalline material. 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.
