Abstract: In one embodiment, a polymeric sheet, comprising: a foamed layer comprising a polymeric material, wherein the polymeric material has a Tg of greater than or equal to 100° C.; and wherein the sheet has a weight reduction of 10% to 60%, as compared to a solid sheet of the same geometry and size formed from the same polymeric material. The sheet, at the thickness of 1.0 mm, has a smoke density of less than or equal to 200 particles after four minutes of burning according to ASTM E662-06. The sheet is thermoformable.
