This standard specifies the terms and definitions of vinyl chloride-nano calcium carbonate in-situ polymerization suspension polyvinyl chloride resin, product classification, requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage. This standard applies to polyvinyl chloride resin produced by in-situ polymerization by adding nano-calcium carbonate microemulsion during the suspension polymerization process.
