Suspension PVC Resin (Medium Molecular Weight)
General-purpose suspension PVC resin (K-57) for rigid and semi-rigid extrusion, injection, and blow-molding applications.
K-57 is a medium molecular weight suspension-grade PVC resin offering balanced processing performance for a wide range of rigid and semi-rigid applications. Its controlled porosity and particle size distribution ensure good plasticizer absorption, smooth extrusion, and consistent mechanical properties in pipes, profiles, and molded articles.
Key Features
Balanced molecular weight for versatile processing
Good plasticizer absorption and gelation properties
Smooth extrusion and calendering performance
Consistent bulk density for reliable feeding
Excellent mechanical properties in finished products
Suitable for rigid and semi-rigid formulations
