Closed-cell sponge rubber contains balloon-like cells that prevent the passage of these substances at low pressures.Sponge rubber provides better cushioning than solid rubber but can become over-compressed so that seal failure results.
Sponge rubber is available in different durometers. Seashore Closed-cell sponge rubber in 25 ±5 duro as standard or per request, it is satisfied with most of sealing requirement. As one of EPDM rubber series, it also has anti-weahering, ozone resistance, noise-proof, dust-proof, abrasion resistance, tear resistance and etc.
