SG-3 is a low-viscosity general-purpose suspension PVC resin. It features low polymerization degree, excellent fluidity, outstanding plasticizer absorption performance and stable thermal processing properties. With low volatile matter, low impurity content and high whiteness, this grade ensures stable high-speed extrusion, injection molding processing, and excellent dimensional stability of finished products. It is widely used in soft and rigid PVC profiles, pipes, cable materials, plastic products and other mass-production scenarios, with reliable batch consistency and superior comprehensive processing performance.
