NE Seal stocks high quality silicone sponge rubber and neoprene sponge rubber materials, available by the sheet or roll.
We manufacture precision custom die-cut or water-jet cut gasket seals for a variety of applications using silicone and neoprene sponge rubber materials.
Silicone Sponge Rubber and Neoprene Sponge Rubber are flexible, elastomeric materials used for sealing gaskets. Silicone and neoprene foam sponge materials provide great cushioning support for most any surface areas.
NE 501 - Neoprene® Sponge - Chloroprene (CR) Closed Cell
||Distinct advantages are low water absorption, providing a tight seal and the ability to conform to curves and corners without bridging or creasing. Generally attacked by strong oxidizing acids, esters, ketones, chlorinated aromatic and nitro hydrocarbons.|

According to your application needs, sponge rubber materials are available in several densities; low, medium and high.
Open Cell Sponge materials have interconnecting cells, under pressure the air to passes through material quickly. When the pressure is relieved, the air is drawn back into open cell quickly as well. Open Cell Sponge Rubber materials rebound quickly, returning to original thickness.
Closed Cell Sponge materials have non-interconnecting cells containing air. When force is applied, the cells cause the air to pass slowly through cell membranes. When pressure is relieved, some cells will quickly return to original thickness, some cells will slowly return to original shape, and some cells will remain as they were under pressure. Though, silicone sponge rubber materials are known to be more resilient to this sort of deformation.
