SEALGUARD PLUGS / SLEEVE RINGS

SEALGUARD PLUGS / RINGSLEEVE is a water-expandable rubber on a polychloroprene basis (CR=chloroprene rubber, neoprene), that is produced from chloroprene by radical emulsion polymerisation. It is available in many different standard diameters, and is used as a plastic sealing material in structural and civil engineering as well as in tunneling. The expanding property results from the irrevocable bonding of polyurethane based water-expandable polymer resin with the CR matrix by vulcanisation. SEALGUARD RINGSLEEVE can expand up to 1300 vol.% by absorbing water, whereby the CR-matrix provides for strength of shape during the expanding process.
