  • Core enclosures and methods for making the same
    Publication number: 20020154873
    Abstract: Core enclosures suitable for use in a fiber optic cables and having water-blocking capabilities as well as methods for forming such core enclosures are disclosed. The core enclosures include a mixture of a superabsorbent polymer and a plastisol, the plastisol comprising a thermoplastic resin and a plasticizer. Also disclosed are fiber optic cables which include these core enclosures. The core enclosures protect optical fibers from damage caused by water by blocking and retaining water that has entered into a fiber optic cable and by preventing water from penetrated through the core enclosure to optical fibers enclosed within.

  • Coated substrate having a water swellable coating
    Patent number: 6287679
    Abstract: A method for forming a water swellable coating and a water swellable coating for forming a coated substrate are provided. The water swellable coatings are semi-gel dispersions of particulate superabsorbent polymer in a polyvinyl chloride plastisol. A dispersion is formed from the polymer and plastisol, then contacted with a substrate and heat cured to a semi-gel state. The coatings are capable of swelling in the presence of water to protect the substrates from water penetration, block water from penetrating the coatings to reach other substrates or to retain water to prevent leakage.
