Silicone Sponge Cord Manufacturing Capabilities

We are able to supply silicone sponge cords in the following sizes:

  • From 2mm minimum diameter
  • To 80mm maximum diameter

We are able to offer minimum order quantities as low as 10m, depending on the diameter of the sponge cord. We are also able meet the demand for large production runs of many thousands of metres. Silicone sponge cord can be supplied in a range of coil lengths depending on its size.

Silicone sponge contains blowing-agent additives to give it its cellular structure, these result in a natural off-white colour. However, we are able to pigment silicone sponge to achieve most colours. We can offer colours match to RAL and Pantone numbers as well as your samples.
