PVC K70
PVC K70.
PVC is a premium extrusion-grade PVC homopolymer formulated for superior performance in wire extrusion and calendar processing applications. With an enhanced degree of polymerization (1290 ± 30) and K-value of 70, PVC delivers exceptional clean surface finish, bright coloring, and consistent processing characteristics. The superior particle structure and optimized properties make it the preferred choice for high-quality electrical wire insulation, automotive interior components, and high-pressure hose applications. Degree of Polymerization: 1290 ± 30 K-Value: 70 Primary Applications: Wire extrusion compounds, automobile interior products, high-pressure hose, electrical wire insulation Secondary Applications: Flexible vinyl compounds, protective tubing, specialty extrusion products, calendered films
