Boltaron® 4205 extruded proprietary thermoplastic alloy sheet was developed for higher in-service temperature interior aircraft applications. It meets FAR 25.853(a) test criteria, and its heat deflection temperature exceeds 200°F at 264 psi load (93°C at 1.8 MPa).

The material also offers a solid balance of overall performance on impact strength
and rigidity, and resists abrasion, staining, chemicals and cleaners. In thermoforming,
Boltaron® 4205 exhibits exceptionally high consistency, with uniform surface appearance and wall thickness integrity even in deep draws and sharp corners.

Boltaron’s unique custom production capabilities also afford designers a comprehensive range of colors and the industry’s widest range of textures for aircraft interior components.
