CABLOC® polymers protect power and communication cables from damage through penetration of water. Penetrating water is absorbed immediately and is firmly bound through swelling. Defects and damaged parts are sealed effectively, thus preventing further penetration of water.
For the production of swellable cable components Creasorb offers new, liquid, solvent free, crosslinkable polyacrylates (SAP) as well as traditional crosslinked superabsorbent granules with the trade name CABLOC®. CABLOC® polymers cover all technical and economic demands of the rapid and progressive developments in the cable industry.
CABLOC® polymers are crosslinked or crosslinkable homopolymers or copolymers with water binding groups. In their dry form these polymers are insoluable in water but highly swellable.
In the event of water ingress into a cable manufactured with swellable components, the CABLOC® superabsorbent polymers immediately swell to many times their original dry particle size. This effect leads to effective prevention of further water penetration. Due to the rapid swelling of CABLOC® polymers, voids within the cable are sealed immediately, preventing water movement, keeping the potential damage localized.
