Silicone Rubber Sponge Square, Strip And Cord

The sponge rubber Product is a general purpose sponge cord used in various sealing applications. It is soft and compressible and can be supplied in coils, cut lengths or vulcanised into O-rings. We offer hollow and solid sponge rubber cord from various materials as EPDM, NBR, Silicone, Neoprene etc.

Sponge rubber cord is resistant to weathering, aging and some chemical substances. Basically sponge rubber cords can be used within the temperature range of the base elastomeric material they are made of. Sponge rubber usually achieves a hardness of 20 - 30 Shore A.

Extruded sealing sponge rubber cords are where necessary soft, pliable and elastic, and have a relatively low weight even with large diameters. Sponge sealing cords are very reliable in applications where it is not possible to use sealing cords made of compact solid rubber. Smaller quantities (by the meter) are available from our warehouse stock upon request.
