PVC is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds or under the action of light or heat according to the free radical polymerization mechanism. PVC particles are a commonly used plastic raw material, also known as polyvinyl chloride particles, which are granular substances formed after polyvinyl chloride (PVC) is processed. PVC particles are a common plastic material with good weather resistance, chemical corrosion resistance and mechanical strength.
