Cable sealed with a polyurethane resin and sealing process of the same

摘要

This invention relates to a cable whose inner opening space has been sealed with a polyurethane resin formed with a polyurethane resin-forming sealing material comprising components (A) and (B). (A): a component comprising a dispersion (1) of a water-insoluble water absorbent resin (D) or its hydrogel in a polyol (C), wherein said resin (D) is formed by polymerizing in the polyol (C) a water soluble monomer or its precursor and crosslinking agent and/or polysaccharide; and (B): a component comprising an organic polyisocyanate (2); and sealing process of the same. This invention provides a cables having an excellent water preventing property without the risk of falling-off of the sealing material at the time of cable connection.
