Lehigh’s MRP is used in a wide range of polyurethane systems and applications, providing numerous benefits that can improve performance while reducing costs. Lehigh recently developed a new micronized rubber powder, MicroDyne™ MD-408TR, specifically for the polyurethane market. MD408TR features a tighter particle size distribution, which allows for higher loadings, greater consistency and increased cost savings.

Typical applications are in the automotive industry, where MRP is used in armrests, seat headrests, seat bottoms, seat backs and foam seals under instrument panels. Soft foam applications can also be used in flooring to provide insulation and protection from moisture.


• Significant cost savings
• Equal or higher quality of foam system
• Improved foam cell structure
• Improved noise vibration and harshness (NVH) performance
• Improved thermal conductivity
