Kydex® 6185 High Temperature Aircraft Grade – 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. It meets FAR 25.853(a) for use in aircraft interior parts. Maximum recommended service temperature is approx. 180 – 195°F (82-90°C) depending on thermoforming technique and application.
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. It meets FAR 25.853(a) for use in aircraft interior parts. Maximum recommended service temperature is approx. 180 – 195°F (82-90°C) depending on thermoforming technique and application. Kydex 6185 sheet is designed primarily for use in small aircraft interiors particularly the interior of helicopters which often experience temperatures in excess of 180°F (82°C), but also is appropriate for other applications where high in-service temperatures may occur.
Aircraft interior components examples include: air ducts, window reveals, instrument panels, toilet shrouds, armrests, etc.
Kydex 6185 is available in gauges from .040″ (1.02mm) and up in eight distinctive textures and custom colors.
Kydex 6185 meets the requirements of the Federal Aviation Administration paragraph FAR25.853(a) in all gauges for vertical burn.
Heat Distortion Temperature (HDT), which is one measure of the material’s maximum service temperature is 180°F (82°C) unannealed at 264 psi (1.8MPa) and a high 195°F (90°C) after annealing. In-use temperatures should not exceed this range of temperature. The affect of temperature on a material is highly dependent on part size, internal stresses, and loadings.
Excellent forming properties result in uniform wall thicknesses and crisp detail, plus easy machining and fabricating using conventional methods, further expanding finished part possibilities.
