  • Patent number: 5844021
    Abstract: Disclosed are sealant compositions and electrical connectors having excellent low temperature repairability and outstanding sealing ability at both high and low temperatures. The preferred connectors contain a sealant composition comprising an elastomeric thermoplastic polymer and an extender for said polymer, said extender constituting a major proportion by weight of said sealant composition and said polymer constituting a minor proportion by weight of said sealant composition, wherein said composition preferably has a low-temperature wire insertability of at least about 80 mm. Furthermore, the preferred compositions are both slump and spew resistant over the operating temperature range of the connector.
    Type: Grant
    Filed: May 11, 1995
    Date of Patent: December 1, 1998

  • Patent number: 5741843
    Abstract: Disclosed are sealant compositions having excellent slump and spew resistant, even at relatively high operating temperatures for electrical connectors. The sealants, which are flowable at such elevated temperatures, comprise two essential components: elastomeric thermoplastic polymer, preferably an organic polymer composite comprising diblock and triblock copolymers, and extender for the polymer. The extender may comprise a primary and a secondary extender, such as polybutene oil and mineral oil, respectively.
