PVC suspension resin is a white thermoplastic powder produced by suspension polymerization with good chemical resistance, corrosion resistance, and dielectric properties. With appropriate additives such as plasticizer and stabilizer, it processes into a wide range of finished products. - What grades of PVC resin do you offer? Dingnuo offers PVC suspension resin in 8 general grades from SG-1 to SG-8, plus matting resin variants in SG3 and SG5. Each grade differs in K-value, viscosity, polymerization degree, and typical applications. - How do I choose between SG3, SG5, SG7, and SG8? SG3 suits flexible films, cable compounds, artificial leather, hoses, and soft flooring (higher plasticizer absorption). SG5 balances processability and rigidity for pipes, profiles, sheets, and films. SG7 offers lower viscosity for rigid sheets, panels, and flooring. SG8 is a lower polymerization grade for rigid and injection-molded PVC. - What plasticizer types are available? Dingnuo supplies phthalate plasticizers, phthalate-free (non-phthalate) plasticizers, and polymer plasticizers, enabling formulations from general-purpose flexible compounds to low-phthalate and high-permanence applications. - What are polymer plasticizers used for?
