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.

Glass Transition Temperature
EPU 41 has excellent color fastness after UV aging.
Cold Temperature Performance
EPU 41 retains its elastomeric properties to -10 °C temperatures.
EPU 41 has passed requirements for biocompatibility according to ISO 10993-5 and -10.
Elastomeric Polyurethane Applications
These applications combine a need for high elasticity, tear resistance, and energy return, in addition to isotropy, great surface finish, and accuracy.
Bouncy elastomeric lattices maximize comfort with precision tuning of energy return. EPU 41 excels in these applications thanks to its high elasticity, tear resistance, and cycle fatigue resistance.
