ActivePlastics - PVC resins - Determination of compacted apparent bulk density
塑料 氯乙烯均聚和共聚树脂 振实表观密度的测定
Application Summary AI generated
This standard specifies a method for determining the compacted apparent bulk density of polyvinyl chloride (PVC) resins. It is applied in the plastics industry for quality control and material specification, particularly for PVC homopolymer and copolymer resins used in processing applications like extrusion and molding. The test measures the density after mechanical tapping, which helps predict flow behavior and packing efficiency during manufacturing.
