9250; 9250C
FAR-Rated High Temperature-Resistant Light-Blocking Sheet
Boltaron® 9250 and 9250C are proprietary, thin gauge thermoplastic sheet products that combine maximum light-blocking characteristics with high temperature resistance for aircraft window shades.
9250 is a single color sheet, and 9250C features a double color construction. They offer durability and uniform thermoforming characteristics, and resist abrasion, stains and many chemicals.
Both also meet stringent FAR flammability criteria.
