PVC K67

PVC K67.
PVC is a suspension-polymerized PVC homopolymer offering exceptional versatility for both soft and rigid product manufacturing. With a balanced degree of polymerization (1000 ± 30) and K-value of 65–67, PVC provides excellent mechanical properties in rigid applications while maintaining superior surface characteristics in flexible products. The controlled particle size distribution ensures smooth processing and consistent quality across pipes, cables, sheets, hoses, and rigid construction profiles. Degree of Polymerization: 1000 ± 30 K-Value: 65 (67) Primary Applications: Pipes, cables, leather sheet, hose, rigid sheet, wrap film, window sash Secondary Applications: Flexible and rigid vinyl compounds, building materials, electrical insulation, general-purpose vinyl products
