The manufacturing process of rigid PVC pipe

PVC is polymerized from vinyl chloride monomer. Because 57% of its molecular is chlorine, therefore, it consume less oil compared with other plastics at the same quality. However, because of its high density and consume its energy in the process of producing chlorine. So that PVC pipe lost advantages in many applications. The most ued PVC production process is the polymerization production process. Put pure water, liquefied VCM monomer and dispersing agent into the reaction vessel, followed by addition of initiator and other additives. VCM monomer will generate into PVC particles by polymerization reaction after heating up to a certain temperature. Continued agitation will uniform size of the particles, and the resulting particles are suspended in the water.
