EPU 40

Highly elastic, tear resistant, and energy damping

Highly elastic, tear resistant, and resilient

EPU 40 offers a combination of tear strength, energy return, and elongation making it perfect for impact absorption, 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.
