Cost Efficiency
& Decarbonization
Micron-sized "balloons" that expand 80-100 times when heated, creating closed-cell structures with densities below 20 kg/m³. Ideal lightweight filler and physical foaming agent for plastics, rubber, coatings, leather, and more. Works with injection molding, extrusion, and coating—no equipment changes needed.
Why Physical Foaming?
✅ Lightweight & cost reduction
✅ High resilience
✅ Surface modification
✅ Eco-friendly

High-concentration microspheres in EVA/SBS carriers. Expands instantly during processing — dust-free, odorless, no equipment modifications required. Perfect for footwear, toys, and molded parts.
