SEKISUI SPI KYDEX® 5555HI Thermoplastic sheet
Categories:	Polymer; Thermoplastic
Material Notes:	KYDEX® 5555HI is a proprietary, high performance thermoplastic sheet with integral color specifically engineered to improve aircraft passenger safety. KYDEX® 5555HI is designed to provide material deformation when used in components subjected to HIC (Head Injury Criterion) testing for increased passenger safety. It exceeds the flammability and smoke development requirements outlined in Federal Aviation Regulations (FAR) 25.853 paragraphs (a) and (d). KYDEX® 5555HI exceeds a 55/55 heat release level and 150 smoke development that allows the product to be used as a stand-alone material or within bonded build-up constructions. Suggested Application: Seat parts Bulkhead laminates Life vest shrouds Passenger service units Monitor Shrouds Armrests Molding strips Tray tables Kick panels Bonded build-ups Features: Improved impact properties over traditional thermoplastics for HIC compliance seating requirements Reduces cost of compliance by decreasing the total number of expensive and time consuming 16g tests required Increases design freedom to create more complex seat geometries Decreases weight by eliminating the need for heavy reinforcements or thick gauges Exceeds the stringent requirements of FAR 25.853 paragraphs (a) and (d) in all thicknesses and colors, which allows for bonded build-up constructions Excellent formability and fabrication characteristics Processes similar to KYDEX® 5555 Allows for tight tolerance control Available in a wide range of integral colors Information provided by SEKISUI KYDEX, LLC.
