PVC Suspension S-70

PVC Suspension S-70 is commercially available in different grades and K-values depending on the required final product properties. Standard S-70 grade generally has a K-value around 66–68 and is mainly used for rigid PVC applications such as pipes, profiles, sheets, window frames, fittings, and industrial components. Higher molecular weight suspension PVC grades such as S-65 and S-75 are selected when different melt strength, impact resistance, or processing characteristics are required. Lower K-value grades provide easier processing and better surface appearance, while higher K-value grades offer improved mechanical strength and durability. PVC S-70 is widely used in construction materials, electrical products, packaging components, household goods, automotive parts, and many other applications where chemical resistance, long service life, and cost efficiency are required.

The main advantages of PVC Suspension Resin S-70 include excellent chemical resistance, high rigidity, good electrical insulation properties, weather resistance, flame retardancy, and strong compatibility with stabilizers, lubricants, impact modifiers, and other formulation additives. Due to its stable quality and versatile performance, PVC S-70 is an important raw material for manufacturers producing export-quality PVC products. The resin can be customized according to customer requirements regarding particle size, bulk density, whiteness, residual VCM content, and packaging options. With its wide industrial acceptance and consistent processing performance, PVC Suspension S-70 remains one of the preferred PVC resin grades for global plastic manufacturing industries.
