  • Flexible filament device with pressure-sensitive flame retardant adhesive
    Patent number: 5981064
    Abstract: A flexible energy-carrying circuit device has reduced flame retardancy while maintaining desired levels of adhesion between the energy-carrying filaments and the substrate with use of a flame-retardant pressure-sensitive adhesive comprised of a polymer of one or more acrylic esters with bromine and phosphorous compounded into the polymer to provide an adhesive having inherent flame retardancy. Small quantities of antimony trioxide may be dispersed in the adhesive to enhance flame retardancy.
