SEKISUI SPI KYDEX® 6185 Thermoplastic
Categories: Polymer; Thermoplastic

Material Notes: High temperature aircraft sheet

Kydex® 6185 is a proprietary thermoplastic sheet with improved heat distortion temperature (HDT) for higher in-service temperatures while providing excellent extensibility, good impact resistance and excellent solvent resistance.

KYDEX® 6185 meets FAR 25.853 (a) (i) + (ii) for use in aircraft interior parts. Maximum recommended service temperature is approximately 85 - 90°C (185 - 195°F) depending on thermoforming technique and application.

Suggested Applications:

  • Aircraft Interiors
  • Equipment Housings


  • Available in thicknesses from 1.00 mm (0.040 in) in eight distinctive textures and custom colors
  • Meets the requirements of the Federal Aviation Administration FAR 25.853 (a) (i) + (ii) in all thicknesses for vertical burn
  • Heat distortion temperature (HDT) is 85°C (185°F) unannealed at 1.8 MPa (264 psi) and a high 90°C (195°F) after annealing
  • Excellent forming properties, uniform wall thickness and crisp detail
  • Easy machining and fabricating using conventional methods and equipment
