T/CCASC 3002-2023 Dynamic thermal stability test of polyvinyl chloride (PVC) using double roll roll mill plasticizing method
Abstract
This document specifies a dynamic thermal stability test method for determining the appearance color changes of a series of polyvinyl chloride (PVC) samples under different plasticating times when the mixture mainly composed of PVC is plasticated by a twin-roll mill.
This document is applicable to determining the dynamic thermal degradation resistance of PVC (SG3, SG5, SG7, SG8 types) by evaluating its thermal stability based on the appearance color changes of the samples under different plasticating times within a specified temperature range. This document is not applicable to general-purpose PVC resins produced by the bulk method.
