EPU 41 is a production-scale elastomeric material that is especially well-suited for elastomeric lattices where high resiliency is needed. EPU 41 has higher resilience (energy return) and better retention of elastomeric properties than EPU 40 at temperatures > -10°C. It is comparable to commercial TPUs with a Shore A hardness of 70. EPU 41 has excellent color fastness after UV aging. EPU 41 retains its elastomeric properties to -10 °C temperatures, and has passed requirements for biocompatibility according to ISO 10993-5 and -10.
