PORON® Microcellular Urethane has an excellent set resistance which enables durable, long term performance for gaskets, sealing and cushioning. It has a unique memory foam like design that provides low level impact absorption. It rebounds slowly when compressed, resulting in a custom fit that supports stability and balance. Poron® will not become brittle and crumble and is non-corrosive to metal. Available in sheets, rolls, stripping, gaskets and with adhesive backing.

Poron® 4701 meets MIL-P-12420.
