Neoprene Sponge Cord

Neoprene Sponge Cord

Neoprene sponge cord is manufactured from a high quality closed cell sponge rubber that is easily compressed and manipulated. This general purpose, flexible, expanded rubber cord offers good resistance to water, ozone and weathering and is suitable for both indoor and outdoor sealing applications.

With a recommended operating temperature of -40°C up to +90°C, the closed cell formation of neoprene sponge is designed to prevent the escape of gas, liquid and air. It is supplied in coils or cut lengths and can be bonded to create an O-ring using cyanoacrylate adhesive (super glue).
