Gulf1s BTDA* forms polyimides that will stand the heat.
When you're up against planning a compact TV set with a big picture or increasing the usable space in a refrigerator, you're up against doing bigger jobs with smaller motors, wires, and electrical devices. And that means heat. Polyimides made from Gulf BTDA fight heat in home appliances, in outer space and in the new generation of aircraft. BTDA can be used to derive outstanding polyimides—laminates with excellent flexural strength after 1000 hours at 600°F, wire
enamels with cut-through temperatures above 662°F, and adhesives and films with similarly outstanding properties. Write for our technical applications bulletin "BTDA in polyimide polymers." It could help you make sure you can stand the heat.
