Seal & Design fabricates closed cell sponge in bun from which is then converted into sheets on our electronically controlled splitting machine. From these sheets, a variety of gasket, sealing and cushioning products are manufactured. We also can apply pressure sensitive adhesives to these closed cell materials, making them even more versatile. Controlled compression and recovery characteristics along with shock absorption attributes provide a highly flexible material with the ability to fill in voids in many applications.
