PORON 4790-92 Polyurethane Foam

Rogers PORON 4790-92 foam is an extra soft, slow rebound foam with a very low closure force.

PORON 4790-92 polyurethane foam provides excellent protection for lower energy impacts.

Softer and with a slow rebound, the material is conformable yet returns to its original shape, allowing for long-term performance.
