The PVC Formula Design Summary
The PVC Formula Design SummaryPure polyvinyl chloride (PVC) resin belongs to a class of strong polar polymer, its intermolecular force is large, which leads to high PVC softening temperature and melting temperature, generally need 160~210℃ to process.In addition, the substituted chlorine group contained in PVC molecules can easily lead to hydrogen dechlorination of pvc resin, thus causing PVC degradation reaction, …
