Rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions. PVC additives need to be added in the processing of plastic pvc pipe fittings manufacturer to be able to meet people's needs to obtain a variety of soft, hard, transparent, good electrical insulation, foam, and other products, different types of PVC resins and various additives match pvc material combinations can produce different applications. Common is the suspension of production of loose resin, commonly known as SG resin mix.
