Ultra low heat release and smoke density aviation sheet
Introduction
KYDEX® 4545 is a proprietary, high performance thermoplastic sheet specifically formulated to exceed the heat release and smoke density requirements in FAR 25.853 making it an ideal material for composite constructions.
General
Information
KYDEX® 4545 exceeds the flammability and smoke development requirements outlined in Federal Aviation Regulations INFORMATION (FAR) 25.853 paragraphs (a) and (d). Its low heat release and smoke density offers an enhanced level of safety for interior components while making it an ideal material for composite constructions. Its wide processing window and ease of thermoforming makes it perfect for complex parts.
