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.

CHEMICAL COMPATIBILITY

EPU 40 exhibits low mass gain with many common household chemicals and industrial fluids.

HIGH GLASS TRANSITION TEMPERATURE

EPU 40’s high glass transition temperature and high damping coefficient allow for better damping over a broad temperature window.

BIOCOMPATIBILITY

EPU 40 has passed requirements for biocompatibility according to ISO 10993-5 and -10.

Example Applications

These applications combine a need for high elasticity, tear resistance, and energy damping, in addition to isotropy, great surface finish, and accuracy.
