Koroyd™ < back

Koroyd™ is composed of masses of co-polymer tubes that are thermowelded together and shaped (in the case of helmets) into a honeycomb-like structure that can be integrated into helmet liners.

Upon impact, the Koroyd™ tubes collapse and, like EPS foam, slow and reduce the transmission of energy to the head. As used in helmet liners, Koroyd™ is a single-impact product. It’s currently seeing use in a few cycling helmets in tandem with EPS foam.
