Sponge Cord (Expanded Neoprene)
Expanded neoprene sponge cord is supplied by the metre in a selection of diameters. As a soft compressible material, it is ideal for creating watertight seals, joining into o rings, or making other custom sized gaskets. The ends can be joined together using good quality superglue or contact adhesive.
Manufactured from closed-cell materials, our sponge cord does not absorb water so can be used for making a watertight seal on boat hatches, lockers, car boots, enclosures, and cabinets. Expanded neoprene is also a soft and compressible material that has excellent a resistance to temperature, UV, air and ozone. This makes it suitable for use in outdoor environments that may subject the seal to extreme temperatures or weather conditions.
Sponge cord has also historically been used in replacement of Crittall glazing seals and baco glazing seals on metal greenhouses. As a material suitable for sealing, insulation and vibration dampening, it can reliably be used to cushion the glass against the aluminium frame.
