PVC Resin SG-3

Polyvinyl chloride (PVC) resin appears as a white thermoplastic powder produced by the suspension polymerization process. It is insoluble in water, gasoline, and ethanol, but soluble in ketones, dichloromethane, and aromatic hydrocarbons. PVC resin features good chemical resistance, corrosion resistance, and dielectric properties. With appropriate additives (e.g., plasticizer and stabilizer), it can be converted into a wide range of finished products with tailored physical and mechanical properties. Based on the degree of polymerization, PVC suspension resin is categorized into 8 general grades, ranging from SG-1 to SG-8.

Pvc Resin Sg 3

Pvc Resin Sg 3 is a soft-grade Pvc Suspension Resin widely valued for its excellent flexibility, stable processing behavior, and adaptability in soft PVC manufacturing. Compared with higher SG grades, SG3 resin features a lower polymerization degree, making it especially suitable for products that require softness, elasticity, and smooth surface performance.

Dingnuo supplies high-quality Pvc Resin Sg 3 designed to support efficient production and consistent end-product quality. With reliable particle uniformity and controlled purity, this resin grade performs well in various compounding and plasticizing applications across industrial and consumer sectors.
