Polyvinyl chloride (pvc) for combustion characteristics, flame retardant, Jimie from the fire, the flame is yellow, white smoke, burning plastic softened issued irritating smell of chlorine. Polyvinyl chloride resin is a multi-component plastics, according to different purposes different additives may be added, so as the different compositions, which articles may exhibit different physical and mechanical properties, such as adding or not adding a plasticizer to keep it in There are hardware and software products division. Overall PVC products are resistant to chemical stability, self-extinguishing flame resistance, high abrasion resistance, noise absorber, strength, good electrical insulation, low cost and wide sources of material, airtight performance advantages. The disadvantage is that poor thermal stability, by the action of light, heat, oxygen is easy to aging. PVC resin itself is non-toxic, non-toxic plasticizer if and stabilizer auxiliary material products plastic PVC pipe fittings, harmless to humans and animals. However, generally seen in the market PVC products used plasticizers, stabilizers mostly toxic plastic PVC pipe, so in addition to the products indicated non-toxic formula plastic PVC pipe price, can not be used to dress food . PVC additives need to be added in the processing of plastic PVC pipe, so that people can be prepared to meet the needs of a variety of soft, hard, transparent, good electrical insulation, foam, and other products to match the combination of different types of PVC resins and various additives way can produce pvc materials for different applications. Common is the suspension of production of loose resin, commonly known as SG resin mix.
