ABSTRACT:
A thermoplastic fluoropolymer adhesive composition containing a thermoplastic fluoropolymer, an elastomeric fluoropolymer, a thermoplastic ethylene copolymer and a tackifier, in which the combined amount of ethylene copolymer and tackifier is less than about 30% by weight (based on the weight of the four components) and the ratio of ethylene copolymer is less than about 2:1, has improved sealing performance and flame resistance than similar compositions containing greater amounts of ethylene copolymer and tackifier. The composition is particularly useful for sealing surfaces of uncrosslinked ethylene-tetrafluoroethylene copolymers.
