PVC Introduction


PVC is an abbreviation for polyvinyl chloride (PVC). Its full name in English is polyvinyl chloride. Affected by light, the thermal and thermal stability of heat-polymerized vinyl chloride monomers and polymers is poor. It is decomposed and released at 170° C. Therefore, it must be added. Practical applications of stabilizers to improve light and heat resistance.


PVC is one of the world's largest ordinary plastics production. Although it is currently exceeding abs plastics, it is still due to its low price and other factors, such as pipe fittings, building materials, industrial products, wire and cable, daily necessities, floor tiles, and packaging. Films, sealing materials, foams are widely used, and so on.


The main hazards of PVC materials


PVC itself is not toxic, but most of the materials added to plasticizers, stabilizers, and other materials are toxic. The main plasticizers and stabilizers include dibutyl, dioctyl phthalate and lead lead stearate, which are toxic. The addition of lead stearate as a stabilizer for the contact of PVC materials with ethanol, ether and other solvents will precipitate lead and lead. As a toxic heavy metal, it will cause great harm to human organs. This lead compound is a compound that is regulated by the EU Chemical Agency. If the content of PVC material exceeds 0.1%, sales are prohibited.
