High Polymerization PVC Resin DP-1800

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.

DP-1800

DP-1800 is a high-polymer PVC resin with an average degree of polymerization of 1800 (1650-1850). Compared with general grades, it features superior toughness, excellent impact resistance, and outstanding performance under low temperature and long-term aging conditions, making it ideal for high-performance applications that demand excellent elasticity, weather resistance, and robust physical properties.
