KYDEX® 5555 Technical Data Sheet

Low heat release aviation sheet

KYDEX® 5555 is specifically formulated to meet the safety needs of the aviation industry.

KYDEX® 5555 is a proprietary, high performance acrylic/PVC thermoplastic sheet that meets all fire retardancy requirements INFORMATION set forth in Federal Aviation Regulations 25.853 paragraphs (a) and (d) (old (c)) including low heat release (65/65) in the OSU rate of heat release test. KYDEX® 5555 exceeds the heat release to a level of 55/55. Its excellent properties make it the ideal material to form two-and-three-dimensional aircraft components.

  • Seat parts • Armrests
  • APPLICATIONS • Bulkhead laminates • Window shades
  • Life vest shrouds • Moulding strips
  • Passenger service units • Tray tables
  • Monitor shrouds • Kick panels
  • Available in over 200 developed colours, various surface textures, and eight thicknesses ranging from 0.71mm and
  • up.
  • Very resistant to a wide range of concentrate chemicals, and is therefore easy to clean with aggressive cleaners such
  • as Soft Scrub®, Fantastic®, and citrus-based cleaners such as Citri Kleen®. Ammoniated cleaners should be avoided
  • since they can leave a residue.
  • Meets the stringent requirements of the FAR 25.853 paragraph (d) (replaces para.c), in all thicknesses and colours.
