CarbonResin™ EPU 41

CarbonResin™ EPU 41 is a production-scale elastomeric material that is especially well-suited for elastomeric lattices where high resiliency is needed. EPU is our elastomeric material family. Its combination of tear strength, energy return, and elongation makes it perfect for cushioning, impact absorption, vibration isolation, gaskets, and seals. EPU 41 is our production-grade elastomeric material. EPU 41 has higher resilience (energy return) and better retention of elastomeric properties than EPU 40 at temperatures > -10°C. Offered only in 5-L bulk packaging, EPU 41 will require MMD (meter, mix, and dispense) equipment for proper dispensing of the material in bulk quantities.
