ActivePolyvinyl chloride resins - Test methods for the thermal stability - Whiteness method
聚氯乙烯树脂 热稳定性试验方法 白度法
Application Summary AI generated
This standard specifies a test method for evaluating the thermal stability of polyvinyl chloride (PVC) resins by measuring the whiteness of the material after exposure to heat. It is applied in the plastics industry for quality control and material selection, particularly for PVC compounds used in pipes, profiles, and cables where heat-induced discoloration must be minimized. The method is used by manufacturers and testing laboratories to assess resin degradation resistance during processing or end-use thermal exposure.
