Description
Highly elastic, tear resistant, and energy returning
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. As a production scale offering, EPU 41 is only offered in 5-L bulk packaging and requires MMD (meter, mix, and dispense) equipment for proper dispensing of the material in bulk quantities. It is comparable to commercial TPUs with a Shore A hardness of 70.
