ActivePlastics--Homopolymer and copolymer resins of vinyl chloeride for general use--Determination of plasticizer absorption at room temperature
塑料 通用型氯乙烯均聚和共聚树脂 室温下增塑剂吸收量的测定
Application Summary AI generated
This standard specifies a test method for determining the amount of plasticizer absorbed by polyvinyl chloride (PVC) homopolymer and copolymer resins at room temperature. It is applied in the plastics industry for quality control and material characterization of general-purpose PVC resins used in flexible products like cables, films, and flooring. The test helps manufacturers evaluate resin porosity and processing behavior to ensure consistent plasticizer uptake during compounding.
