Cellular rubber does not absorb any liquid due to the closed cell structure and can therefore be used as a sealing material. It is available as a semi-finished product on rolls and in sheets or as a finished product such as die-cut and extrusion profile. The most diverse qualities and sizes are available here. It is a soft and compressible material by the cell structure and is widely used as a sealing material in, among other things, construction, shipbuilding and industry. Materials such as EPDM, CR (Neoprene®) and NBR (Nitrile®) quality, polyether foam or silicone foam, possibly provided with a fiber reinforced self-adhesive layer.
