**Soft, Durable, Energy-Damping Elastomer**

EPU 43 brings to Carbon’s industry-leading elastomer portfolio a soft, energy-damping elastomer that offers excellent durability under high-cycle flexing. It can be used in applications where foam is traditionally used, but with lower density, increased airflow, and much higher durability. 

Ideal applications include comfort liners inside helmets and impact padding for safety gloves. EPU 43 prints with moderate green strength, which allows for a broad set of possible production shapes with high yield.

# Thermal Processing

Some resins may crystallize or freeze at lower temperatures requiring a thermal processing step, also known as incubation, prior to dispensing.
