What makes Enkayse® special?

Enkayse®is a temperature-stabilising formula for PU foams, elastomers, and rubbers used in impact protection.
It enables materials to meet safety standards that would otherwise be out of reach.
That’s how we built the world’s first certified cycle helmet without sacrificial foams like polystyrene.
It’s how we delivered a 5mm rugby headguard that outperforms rivals more than twice its thickness.
Known as “Amnesic Foam,” Enkayse® leaves no memory imprint — no dents, no degradation.

The Enkayse® range

There are multiple formulations of Enkayse® that can be used across a variety of protective equipment.

Duro

Active

Flex

Enkayse attenuates impacts more than other other foams on the market

The chart shows a reduction in linear acceleration from a 300g impact at body temperature (37.5C) with various foams

Impact data verified by independent expert Dr. William G. Proud, Director of the Institute of Shock Physics and Reader of Shock Physics at Imperial College London through Imperial Consultants

Enkayse® performs best at body temperature, better than poron and D3O

Body Heat Isn’t Optional. Your Protection Shouldn’t Fail Because of It.

This graph compares Enkayse with two widely used impact foams. While all materials perform similarly at room temperature, the foams lose effectiveness in heat and cold—exceeding the injury risk threshold. Enkayse remains stable and protective across all temperatures tested.

Enkayse® doesn't break like EPS. Increasing the life span of a cycle helmet

Everyday drops breaks EPS. Not Enkayse.

This graph shows a series of low-level impacts applied at one-minute intervals. While EPS degrades steadily, Enkayse® maintains consistent performance — and given more time between impacts, it would fully recover.
