A deicer includes an aircraft structure (10) and an outer layer (14) with a sheet having a brittle point lower than -40 °C (-40 °F). The sheet includes a polyether urethane elastomer. A deicer includes an aircraft structure (10) and an outer elastomer layer (14). The outer elastomer layer (14) includes a non-woven fabric having polyether urethane fibers and one of (1) a carbon allotrope material (26) aligned with at least one of the polyether urethane fibers (24) and (2) a polyester urethane composition located on a portion of the non-woven fabric. A method of forming a layer of a deicer boot includes forming a polyether urethane elastomer sheet having a brittle point lower than -40 °C (-40 °F) and incorporating the polyether urethane elastomer sheet onto an aircraft structure (10).
