**Highly elastic, tear resistant, and resilient**

EPU 40 offers a combination of tear strength, moderate energy return/damping, and elongation making it perfect for vibration isolation, gaskets, and seals. It is a good choice for applications where high elasticity and tear resistance are needed. 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.
