ABSTRACT:
A plastic sheet capable of being shaped by a cold room temperature tool, said sheet being a semi-rigid thermoformable plastic foam doped with carbon black having a concentration within a range of 0.0000081 to 0.0081% by weight of the foam. And a method of forming a product from such sheet by heating it to its thermoforming temperature range by infrared (IR) heat and placing and compressing the sheet between mold parts of a cold tool, the IR heat preferably being generated by quartz lamp electric heaters.
