Thermally Conductive Films

Aavid, Thermal Division of Boyd Corporation Thermally Conductive Films are flexible materials used to conduct heat from a surface. The films are commonly made of polyimide, a transparent thermoset polymer with excellent physical and electrical isolation properties. The films are lightweight and can withstand harsh environments, adding ruggedness to any product.
