Suspension Polyvinyl Chloride (PVC) Resin is crafted via suspension polymerization, where vinyl chloride monomer disperses in water with suspension dispersants, aided by mechanical stirring. Initiated by a free radical initiator, the process involves steam stripping for residual monomer removal and centrifugal drying. Renowned for its versatility, it's used in extrusion, calendering, blow molding, injection molding, and foam molding, yielding a spectrum of flexible, rigid, and foamed products. This method, crucial in PVC production, employs water as the continuous phase, with dispersants easing tension between vinyl chloride monomer and water.
