Abstract
A fusible flame retardant sealant composition comprised of a homogeneous mixture of polyvinylidene fluoride, methacrylate polymer, and antimony oxide is disclosed. In the preferred embodiment, the sealant composition also contains zinc oxide. The sealant composition as disclosed herein is used to make fusible sealant inserts for preinsulated electrical connectors having a heat recoverable sleeve. The connectors are essentially comprising a conductor connecting means positioned within the heat recoverable sleeve, the conductor connecting means being designed to receive and electrically connect two or more electrical conducting members, the members being inserted from the ends of the sleeve, and one fusible sealant insert member made of said composition positioned near each one of the open ends of the sleeve. Upon application of sufficient heat to the sleeve, the sleeve recovers around the conductor connecting means and the electrical conducting members, and the fusible sealant insert members soften, conform and adapt to the conducting member, adhere to the conducting member and the sleeve, and seal the interstices between the conducting member and the recovered sleeve. The resulting seal is flame retardant and resistant to corrosive chemicals such as jet fuel and lubricant.
