GB/T 21989-2008 《Plastics - Poly(vinyl chloride)pastes - Determination of apparent viscosity using the severs rheometer》 Related products
The GB/T 21989-2008 standard specifies a method for determining the apparent viscosity of polyvinyl chloride (PVC) pastes using the Severs Rheometer. The standard applies to the determination of rheological properties of PVC pastes, through which the flow behavior of PVC pastes at different shear rates can be evaluated. This is of great significance for quality control and process optimization in plastics processing.
