Exceptionally high impact resistance for durability and long service life. Comprehensive color range and the industry's widest range of textures expand design freedom.

BOLTARON 4330 Seat PArts BOLTARON 4330 Damage Resistant BOLTARON 4330 Electrical Enclosure
Compared to other FAR 25.853(a) rated thermoplastic alloy sheet products, Boltaron® 4330 offers an exceptionally high Izod impact strength of 18 ft-lb/in. (953 J/m) for longer service life in aircraft interior components.

This proprietary extruded thermoplastic alloy sheet also expands design freedom with a full range of colors and the widest range of textures in thermoplastic alloy materials. Boltaron's unique custom production capabilities also include the ability to manufacture cost-effective low minimums with fast turnaround.

Boltaron® 4330 also features consistently uniform surface quality, and maintains its wall thickness during thermoforming even in deep draws and sharp corners.

Overall, it offers an unequalled combination of performance and design freedom coupled with both FAR 25.853(a) and UL 94 V0 flammability ratings. Its versatility makes it ideal for applications from aircraft interiors to electrical enclosures, especially in damage-prone environments.

(Note: For aircraft parts larger than 1 sq ft (305 sq mm) requiring an OSU 65/65 rating,.please specify Boltaron® 9815E sheet)
