Low heat release aviation sheet
Introduction
KYDEX® 5555 is specifically formulated to meet the safety needs of the aviation industry.
General
Information
KYDEX® 5555 is a proprietary, high performance acrylic/PVC thermoplastic sheet that meets all fire retardancy requirements 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.
Suggested
Applications
- Seat parts
- Bulkhead laminates
- Life vest shrouds
- Passenger service units
- Monitor shrouds
- Armrests
- Window shades
- Moulding strips
- Tray tables
- Kick panels
Features
- Available in over 200 standard colors, a variety of surface textures, and eight thickness options ranging from 0.71 mm and up.
- Highly resistant to a wide range of concentrated chemicals, making it easy to clean with strong cleaners such as Soft Scrub®, Fantastik®, and citrus-based products like Citri Kleen®. Avoid ammoniated cleaners, as they may leave a residue.
- Meets the stringent requirements of FAR 25.853 paragraph (d) (replacing paragraph c) across all thicknesses and colors.
