GB/T 3402-1994
AbolishedDesignation of homopolymer and copolymer resins of vinyl chloride
氯乙烯均聚物和共聚物树脂命名
Application Summary AI generated
This standard specifies a nomenclature system for homopolymer and copolymer resins of vinyl chloride based on their intrinsic viscosity, apparent density, and plasticizer absorption. It is applied in the Chinese plastics industry for the classification, labeling, and specification of PVC resins used in manufacturing pipes, profiles, films, and cables. The naming convention ensures consistent material identification for procurement, quality control, and technical communication between resin producers and downstream processors.
