Boltaron® 4800 sheet, extruded from a proprietary thermoplastic alloy, was formulated specifically for compliance with low smoke and flammability test criteria for aircraft and mass transit interior applications.

This aircraft-rated material meets stringent FAR test requirements for low smoke emissions and flammability for interior components. It also satisfies ASTM E162 and ASTM E662 flammability and low smoke emission criteria and FTA, UMTA and Docket 90A guidelines for passenger rail interiors.

Boltaron® 4800 expands design freedom with a full range of colors and the widest range of textures available in thermoplastic alloy materials. It also improves the service life of interior components with its high impact strength and resistance to stains and cleaning chemicals. The material behaves consistently lot to lot in thermoforming and maintains uniform wall thickness even in deep draws and sharp corners.
