Certificate of Analysis
1. Product Introduction
PVC‑SG5 is a suspension‑polymerized general‑purpose PVC resin with moderate K‑value and molecular weight. It features stable viscosity performance, high apparent density, low volatile content, few impurity particles and excellent thermal stability. Widely used in hard profiles, pipes, fittings, rigid sheets and general‑purpose injection‑molded products, it is the most versatile grade for rigid PVC processing.
