EPU 41
Overview
Highly elastic, tear resistant, and energy returning
EPU 41 is a production-scale elastomeric material that is especially well-suited for lattices where high resiliency is needed. EPU 41 has higher resilience (energy return) and better retention of elastomeric properties at temperatures > -10°C. It is comparable to commercial TPUs with a Shore A hardness of 70.

Thermal Processing
Some resins may crystallize or freeze at lower temperatures requiring a thermal processing step, also known as incubation, prior to dispensing.
Reference this downloadable PDF for instructions.
Part B Salt Crystals
EPU 41 Part B can form salt crystals when left open in contact with air, or when liquid material is left around the mouth of the container. Avoid formation of salt crystals on rim of Part B container with simple lab practices.
- Wipe mouth of container to clean off any resin prior to closing cap.
- Keep container closed when not in use. Part B loaded in an MMD counts as a closed container.
