Abstract: Adhesives comprising: a) 35-85 weight percent of a pressure sensitive adhesive comprising: i) a polymer selected from rubbers and polyacrylate polymers and ii) optionally one or more tackifiers; and dispersed therein b) 15-50 weight percent fire retardant (FR) particles comprising one or more phosphorus-containing compounds selected from organophosphine oxides and organophosphi-nates. In some embodiments, the phosphorus-containing compounds comprise 35-65 weight percent of an organophosphine oxide and 65-35 weight percent of an organophosphinate. The FR particles may have a D50 particle size of 1-120 micrometers, 40-120 micrometers, or 70-120 micrometers. Adhesive films comprising the adhesives described herein may be free-standing adhesive films or adhesive layers comprised in tapes.
