ActivePlastics - Poly(vinyl chloride)pastes - Determination of apparent viscosity using the severs rheometer
塑料 聚氯乙烯糊 用Severs流变仪测定表观黏度
Application Summary AI generated
This standard specifies a method for determining the apparent viscosity of poly(vinyl chloride) (PVC) pastes using a Severs rheometer. It is applied in the plastics industry to characterize the flow behavior of PVC plastisols, which are used in processes like coating, dipping, and rotational molding. The test helps manufacturers control processing properties and ensure consistent product quality in applications such as synthetic leather, flooring, and automotive underbody coatings.
