Product Overview
Small BossSmallBoss PVC Foam Compound for Footwear is a specially engineered flexible PVC compound with integrated chemical blowing agent, designed for injection molding of lightweight, cushioned shoe soles. The compound activates controlled microcellular expansion during processing, reducing sole density by 30-50% compared to solid PVC while maintaining excellent surface finish and mechanical strength.
Available in three grade series: SB-FS-L (Ultra-Light, density 0.4-0.6 g/cm3 for slippers and sandals), SB-FS-C (Comfort, density 0.6-0.8 g/cm3 for casual footwear), and SB-FS-S (Sport, density 0.8-0.9 g/cm3 for athletic and safety shoes). Ca/Zn stabilization system, REACH/RoHS compliant, with custom hardness from Shore A 45 to 80.

· Advantage
Small Boss🔶Uneven Foaming & Unstable Cell Structure
Precision-engineered granules ensure uniform microcellular structure and consistent density across the entire sole, with surface defect rate below 2%.
🔶Thermal Degradation & Yellowing During Processing
Premium thermal stabilization ensures ≥60 min stability at 180°C with a wide processing window (160-200°C), no discoloration or die buildup for extended production runs.
🔶High Density & Excessive Material Cost
Advanced foaming technology reduces density by up to 50% (as low as 0.4 g/cm3), saving 15-20% material per pair and lowering per-unit cost.
🔶Poor Rebound & Compression Set
High-elasticity compound design maintains excellent rebound (>35%) and low compression set, keeping soles comfortable and shape-retaining through extended wear.
🔶Proven Quality Control
Every batch undergoes rigorous QC testing including mechanical properties, dimensional stability, and color consistency. Our ISO-certified lab ensures compound performance matches specifications batch after batch.
· Application
Small Boss🔶Slippers & Flip Flops
Ultra-lightweight one-piece injection molded slippers and flip flops with soft, cushioned feel. Density as low as 0.4 g/cm3 for maximum comfort.
🔶Casual & Fashion Sandals
Fashion-forward sandals and casual footwear with vibrant color options, smooth surface finish, and excellent wear resistance for everyday use.
🔶Sports & Athletic Shoes
Midsoles and outsoles for running, walking, and court shoes with superior energy return, flexing resistance ≥40,000 cycles, and abrasion resistance ≤300 mm3.
🔶Safety & Work Shoes
Durable work shoe soles with optional anti-slip, oil-resistant, and anti-static formulations. Higher density grade (0.8-0.9 g/cm3) for industrial footwear.
🔶Specialty Profiles
Custom extruded profiles for specialized applications in industrial and commercial settings.
🔶Custom Formulations
Tailored compounds developed to meet specific customer requirements for hardness, color, and processing characteristics.
