PVC compound for pipe fitting is polymerized from polyvinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging, acid and alkali resistance, and is very suitable for chemical pipelines. The mixture composed of a certain amount of solid additives (without plasticizers) added to the raw materials of polyvinyl chloride is called rigid polyvinyl chloride (UPVC).

PVC compound for pipe fitting cannot be hot-melted, and its sealing performance is not good; it is a rigid pipe material and has poor shock resistance; it often contains free chlorine, and its value itself is thermally stable.

In modern life, plastic building drainage pipes, water pipes and sewage pipes have been widely used, and polyethylene pipes are becoming the development direction of plastic pipes. PVC compound for pipe fitting was first used by Germany in 1936, and the world's first plastic water pipeline was laid in Britain in 1939. Since then, plastic pipes have developed rapidly, constantly replacing metal pipes or other traditional pipes. In the 1970s, the standardization and serialization of PVC compound for pipe fitting was realized internationally, which greatly promoted the production and application of plastic pipes in various countries.

PVC pipe fittings are made of PVC resin modified by chlorination. It not only preserves the excellent properties of many PVC materials, but also further improves these properties, allowing it to be used in a wider range of applications and has a longer service life. What is the production of PVC pip
