Introduction to PVC Plastics

Polyvinyl chloride plastics are polymerized from vinyl chloride monomers and are one of the commonly used thermoplastics. Its trade name is referred to as "chlorine plastic", and the English abbreviation is PVC.

Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticization temperature, and its mechanical strength is poor. Therefore, it is impossible to use polyvinyl chloride resin to make products. It is necessary to add plasticizers, stabilizers, fillers, etc. to improve the performance, make polyvinyl chloride plastics, and then process them into various products. Polyvinyl chloride is divided into rigid polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added.
