Premium Footwear Raw Material
Engineered by Novos Plastic, our Expandido PVC Compound is formulated for injection molding lightweight shoe soles, sandals, slippers, and casual outsoles. Featuring uniform cellular expansion, it significantly reduces finished shoe weight while providing exceptional cushioning, flexibility, and abrasion resistance.
Request Foamed PVC SampleNovos Plastic Expandido PVC Compound for Shoe Soles is a specialized lightweight foamed PVC sole material engineered for rotary and static injection molding machines. Designed specifically for footwear manufacturers producing casual shoes, sandals, slippers, and sports soles, this compound incorporates high-grade PVC resin, precision-balanced blowing agents, and specialized plasticizers. It achieves significant weight reduction without compromising mechanical strength or structural integrity.
By forming a fine, uniform microcellular internal foam structure wrapped in a smooth, non-porous outer skin, our Expandido PVC granules deliver superior shock absorption, high flexibility, and excellent abrasion resistance. With fully customizable expansion ratios, hardness levels, and color options, Novos Plastic provides global footwear producers with consistent batch-to-batch quality, optimized cycle times, and substantial raw material cost savings.
Our Expandido PVC compound is engineered with specialized blowing agents that achieve controlled internal foaming during injection. This lowers the overall density of the shoe sole, dramatically reducing the finished footwear weight while maintaining necessary stiffness and shape retention for all-day wearing comfort.
The optimized additive package ensures smooth cell nucleation and uniform bubble distribution within the sole core. This microcellular matrix yields excellent energy return, shock absorption, and flex fatigue resistance, preventing sole collapse and deformation even under long-term dynamic impact.
Novos Plastic Expandido PVC compound offers balanced melt viscosity and stable thermal expansion inside the mold cavity. It fills intricate tread patterns completely and creates a clean, smooth outer surface skin with zero sink marks, ensuring crisp visual detailing and strong bonding with upper materials.
By reducing material consumption per pair through foaming technology and maintaining short molding cycle times, manufacturers achieve maximum cost efficiency. We offer custom hardness options (Shore A), tailored expansion rates, and REACH/RoHS-compliant environmental formulations to match your precise production standards.
