SEKISUI SPI KYDEX® FST2 Thermoplastic (discontinued **)
Categories:	Polymer; Thermoplastic
Material Notes:	Fully compliant aviation sheet KYDEX® FST2 is a proprietary, high performance non-PVC thermoplastic sheet specifically formulated to meet all Boeing and Airbus Flammability, OSU Heat Release, Smoke, and Toxicity requirements for aircraft interior components. KYDEX® FST2 meets the flammability and smoke development requirements outlined in Federal Aviation Regulations (FAR) 25.853 paragraphs (a) and (d) and the toxicity requirements for Airbus (ABD0031) and Boeing (BSS7239). Its wide processing window and ease of thermoforming makes it ideal for complex parts. Suggested Applications: Seat parts Armrests Bulkhead laminates Window shades Molding strips Passenger service units Tray tables Monitor shrouds Kick panels Features: Meets the stringent requirements of FAR 25.853(d) in all thicknesses and colors Compliant to ABD0031 and BSS7239 toxicity specifications Excellent formability and fabrication characteristics Allows for tight tolerance control Low gloss Excellent UV resistance Excellent chemical resistance Lighter weight Available in P3 – Velour Matte Values based upon 0.125 in (3.17 mm) sheet unless otherwise specified Pre-drying of KYDEX® FST2 is required prior to thermoforming in order to remove moisture from the sheet.
