Elastomeric Materials

EPU 40

6min

Overview

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.

Crystallization

Uneven resin flow and a swirling, sparkling appearance when dispensing EPU 40 is a sign that the Part A resin component has crystallized as a result of storage below recommended temperatures.

  • Remove the green stopper on the cartridge and look for evidence of crystal formation around the rim of the Part A resin component opening (larger side of the cartridge).
    • If you don't see any crystals on the rim but want to check more thoroughly, dip a thin spatula 1 cm into the resin component, remove the spatula, and inspect the component.
  • If crystallization is present, incubate cartridges per resin protocols in an oven or incubator.
