Closed cell sponge rubber is one of the most versatile materials. Its structure has non-interconnecting cells that contain air. Force applied to these cells squeezes the air through the thin cell membranes. When the pressure is released, some sponge materials rebound quickly and some rebound very slowly or take a permanent deformation. This class of material has many applications in the automotive, appliances, construction, marine, sports, and electrical equipment industries.

Some of the common applications are UL rated lighting gaskets, noise vibration & harmonics pads, wiring harness gaskets, antenna gaskets, air-conditioning seals, humidifier mounting pads, sound equipment padding, Conveyor Belt Cushions, weather-stripping lighting fixtures, pipe wrapping, and Air/Dust/Oil/Water Seals (UL recognized for NEMA applications)
