ActivePlastics-Vinyl chloride homopolymer and copolymer resins-Sieve analysis in water
塑料 氯乙烯均聚和共聚树脂 水中筛分析
Application Summary AI generated
This standard specifies a method for determining the particle size distribution of vinyl chloride homopolymer and copolymer resins using wet sieve analysis in water. It is applied in the plastics industry for quality control and classification of PVC resins, particularly in manufacturing processes where particle size affects processing behavior and final product properties. The test is relevant for raw material inspection and production consistency in applications like pipes, profiles, and films.
