Summary: | A multilayer material, including a compressible polymer foam layer, wherein the compressible polymer foam layer has a density of less than 400 kg/m3, a compression force deflection of 5 to 1,035 kPa at 25% deflection determined in accordance with ASTM D3574-17, and a thickness of less than 3.5 millimeters; and a solid, polymeric flame retardant layer disposed on a first side of the compressible polymer foam layer, wherein the flame retardant layer has a thickness of less than 0.3 millimeters, wherein the thickness of the compressible polymer foam layer is at least two times greater than the thickness of the flame retardant layer; wherein each of the compressible polymer foam layer and the flame retardant layer includes a flame retardant composition, and wherein the multilayer material has a thickness of 3.5 millimeters or less, and a UL-94 rating of V1, preferably V0, HF1, or a combination thereof. |
