PVC

Application:

PVC is one of the two most important plastic materials available today. It is produced at NPC (BIPC site) by suspension polymerization process. PVC compounds of large extent of stabilizers and other additives are able to meet the requirements ofmany applications. --PVC grades produced by NPC with their general information ,applications , and specifications are as follow:
