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.
Claims19
An energy-carrying device comprising:
- a substrate;
- at least one energy-carrying filament;
- a layer of pressure-sensitive adhesive disposed between the substrate and the filament for adhering the filament to the substrate, wherein the adhesive comprises a polymer fabricated with the polymerization of (a) one or more acrylic esters, (b) dibromostyrene, and (c) vinyl phosphonic acid.
