PORON® is a microcellular urethane foam with extremely low compression set. PORON materials are high density, flexible cellular products and are manufactured by continuously casting and curing mechanically frothed urethane intermediates to the desired thickness. By controlling chemistry and density, the properties of PORON® materials can be widely varied.
