Neoprene sponge cord is made from high-grade closed-cell sponge rubber, delivering outstanding flexibility and compressibility. This expanded rubber cord is well-suited for sealing applications where resistance to water, ozone, and weathering is essential, suitable for both indoor and outdoor use.
Capable of performing reliably within a temperature range of -40°C to +90°C, its closed-cell construction effectively prevents the passage of gases, liquids, and air. Available in coils or cut lengths, it can also be formed into O-rings for specific sealing needs.
We stock neoprene sponge cord in a range of diameters. For sizes not shown here, please contact us with your requirements including product code and quantity.
