Materials for Midsoles
Exceptional Rebound, Durability and Softness for High Performance Footwear
INFUSE™ Olefin Block Copolymers (OBCs) from Dow enables you step up your game in cushioning performance for athletic footwear, with midsoles that deliver lightweight footwear with exceptional resilience, durability and softness. The increased dimensional stability of INFUSE OBCs also offers OEMs the potential to reduce production costs while delivering a longer lasting performance midsoles. INFUSE can also be used in other footwear applications, including slippers, sandals, sock liners and more.
Midsole formulations based on INFUSE OBCs provide a variety of benefits and improvements over conventional materials such as EVA:
- Enhanced Resiliency/Rebound
- Better compression set resistance
- Lower Shrinkage
- Excellent low temperature flexibility
INFUSE OBCs offer far greater energy return than typical EVA foams, giving your midsole, sandal, or unitsole a resiliency your customer can feel the moment the try it on.
