This document specifies a method for determining the hot plasticizer absorption of PVC polymers intended for general use (designated "G" in ISO 1060-1) by hot mixing in a planetary mixer and measuring the amount of plasticizer absorbed.
Abstract
Overview
ISO 4574:2019 specifies a laboratory method to determine the of PVC resins intended for general use (designation “G” in ). The test quantifies how much plasticizer a PVC polymer absorbs when hot‑mixed with a plasticizer (commonly ) in a modified planetary mixer and then separated by centrifuging. Results are reported as the at 75 °C and 30 min and the .
