High impact, low heat release aviation sheet
Introduction
KYDEX® 5555HI is a proprietary, high performance thermoplastic sheet with integral colour specifically engineered to improve aircraft passenger safety.
General
Information
KYDEX® 5555HI is designed to provide material deformation when used in components subjected to HIC (Head INFORMATION 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
Applications
- Seat parts • Armrests
- APPLICATIONS • Bulkhead laminates • Moulding strips
- Life vest shrouds • Tray tables
- Passenger service units • Kick panels
- Monitor Shrouds • 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 colours, 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 colours
