Pvc Resin Sg 5

PVC Resin SG-5

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.

Matting SG-5

Pvc Resin Sg 5 is a widely used grade of Pvc Suspension Resin known for its balanced performance, reliable processing characteristics, and broad industrial compatibility.SG-5 is the most widely used and cost-effective general-purpose grade, with an average degree of polymerization of around 1000(981-1135). It offers a well-balanced combination of processability and mechanical strength, making it suitable for extrusion, injection, and calendering applications. Its versatility and competitive pricing make it an ideal material choice for a broad range of rigid and flexible PVC products.
