Abstract

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

Description

technical field [0001] Disclosed herein are textured polymeric sheets, particularly polymeric sheets comprising a foamed core layer or a foamed cap layer. Background technique [0002] Polymeric (eg, polycarbonate) sheet materials are commonly used in railroad and aircraft applications, for example, in seating or cladding applications. These applications often require meeting stringent fire safety requirements such as flame retardancy, smoke density, smoke toxicity and heat release. Polymeric materials, such as polycarbonate, have difficulty meeting heat release requirements for aircraft and rail applications, and often must be combined with other more expensive materials to pass aircraft and rail application tests. Various requirements are placed on the flame retardancy, smoke density, smoke toxicity and heat release characteristics of sheet materials used in the construction of interior panels and components for aerospace and railway applications. [0003] Lightweight po...
