Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature and plasticizing temperature is very close, and the mechanical strength is poor.
PVC plastic is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Its trade name is referred to as "chlorine plastic", the English abbreviation for PVC. Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature and plasticizing temperature is very close, and the mechanical strength is poor. Therefore, it is impossible to use polyvinyl chloride resin to make products, and plasticizers, stabilizers, fillers, etc. must be added to improve performance, made of polyvinyl chloride plastic, and then processed into various products. Polyvinyl chloride is divided into rigid polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added.
