Polyurethane Foam
PORON® ShockSeal™ 4790-79
Overview
PORON ShockSeal polyurethanes provide engineers a thick grade material for gasket design, cushions, spacers or springs. PORON ShockSeal materials absorb as much or more energy when compared to higher density materials. Handheld grades of PORON ShockSeal materials reduce impact force by up to four times that of competitive material and conveniently conform to some of the smallest and most intricate handheld device designs. Industrial grades of PORON ShockSeal materials are recognized by UL Gasketing and Sealing (UL50E/UL508) and Federal Motor Vehicle Safety Standards 302 (FMVSS 302) specifications.
