PVC extrusion-grade granules are specially formulated polyvinyl chloride compounds designed for extrusion processing. They offer stable melt flow performance, good thermal stability, and consistent processing behavior, making them suitable for continuous PVC extrusion production across a wide range of applications.
These PVC granules are compounded with different additives according to the final product requirements. By adjusting stabilizers, lubricants, plasticizers, and processing aids, extrusion-grade PVC compounds can be matched with different extrusion equipment and end-use products, helping manufacturers achieve stable output and uniform product quality.
Rigid PVC extrusion-grade granules
Rigid PVC extrusion compounds contain heat stabilizers and lubricants, with no plasticizer or only a very low plasticizer content. They are commonly used for producing:
PVC pipes and fittings
PVC profiles and sections
PVC sheets and panels
Window and door profiles
Products made from rigid PVC extrusion-grade granules feature high mechanical strength, good dimensional stability, and excellent weather resistance, making them suitable for construction and industrial applications.
Flexible PVC extrusion-grade granules
Flexible PVC extrusion compounds contain sufficient plasticizers to provide softness and elasticity. Typical applications include:
PVC hoses and flexible tubing
Sealing strips and gaskets
Cable insulation and sheathing
Protective covers and flexible profiles
Flexible PVC extrusion-grade granules offer good flexibility, abrasion resistance, and reliable electrical insulation performance for industrial and electrical uses.
During extrusion, PVC extrusion-grade granules need to be properly matched with processing parameters such as:
Screw design and screw speed
Barrel and die temperature
Cooling and calibration conditions
Proper processing control helps ensure smooth extrusion, stable output, uniform surface quality, and consistent physical properties of the finished PVC products.
With reliable formulation and consistent processing performance, PVC extrusion-grade granules are widely used in pipe extrusion, profile extrusion, hose extrusion, and cable manufacturing, providing a cost-effective and versatile solution for PVC extrusion applications.
