Questions & Answers
Polyvinyl chloride granules are made from: PVC-E-74, PVC-E-70, PVC-E-67, PVC-E-65, PVC-E-62, PVC-C-72, PVC-C-71, PVC-C-70, PVC-C-68, PVC-C-67, PVC-C-66, PVC-C-65, PVC-C-60, PVC-C-58, PVC-O, PVC-M, PVC-U, K67, SG8, SG5.
ASTM D1755 is a standard for PVC resins used in the production of granules and compounds. This standard establishes requirements for vinyl chloride homopolymers in powder form intended for further processing and mixing into thermoplastic composites. It covers the following: aqueous extract conductivity control, bulk density, particle size distribution, viscosity classification, batch quality control, sampling methods, raw material requirements, and PVC resin type classification.
ISO 1060-1 defines a classification and designation system for PVC resins and granules. It takes into account resin structure, processing type, application area, and polymerization method. This standard is intended for the standardization of manufacturer designations, classification by process characteristics, and the unification of PVC grades.
ISO 1183 - Determination of the density of plastics. This standard is used to control the density of finished products and PVC granules. Test methods: hydrostatic weighing, pycnometric method, and immersion method. Monitored parameters: change in density after processing, specific gravity, and true density.
