Suspension PVC Resin (High Molecular Weight)
High molecular weight suspension PVC resin (K-67) for high-strength rigid applications requiring superior mechanical performance.
K-67 is a high molecular weight suspension-grade PVC resin designed for demanding rigid applications where mechanical strength, impact resistance, and chemical resistance are critical. Its higher degree of polymerization delivers tougher, more durable finished products while maintaining good processability in extrusion and injection molding.
Key Features
High molecular weight for superior mechanical strength
Excellent impact resistance in rigid formulations
Good chemical and weather resistance
Suitable for pressure pipe and high-strength profiles
Consistent porosity for reliable processing
Low VCM residue — meets stringent health standards
