AI Overview
Modified PVA 552 (PVOH 552) is a specialized, low-hydrolysis (typically ~53–55 mol%) polyvinyl alcohol grade, often used as a high-efficiency secondary suspending agent for vinyl chloride suspension polymerization. It is engineered to improve PVC particle structure, porosity, and batch-to-batch consistency, providing superior performance over standard PVA.
