Expansion PVC FAQ
What is the primary benefit of Expansion PVC?
+
Expansion PVC is designed to create a uniform micro-cellular structure within the material, offering a significant reduction in density while maintaining excellent surface smoothness and structural strength.
How does it differ from Air Blowing PVC?
+
Unlike Air Blowing PVC which relies on injected air, Expansion PVC uses chemical blowing agents or microspheres within the compound to expand during heating, resulting in much finer and more uniform internal cells.
What are the typical applications for this compound?
+
It is widely used for premium slippers, lightweight outsoles, and technical profiles where dimensional stability and a high-end matte finish are required.
Is the expansion ratio controllable?
+
Yes. Our formulations allow for precise control over the expansion rate by adjusting processing temperatures, ensuring consistent product dimensions and weight.
Does Expansion PVC require special machinery?
+
While it can be processed on standard injection molding machines, achieving optimal micro-cellular results depends on precise temperature control across the screw zones.
