Polyimide film class H has the best thermal properties of films available and is usable in the temperature ranging from 180° to 350°. Its physical properties are excellent and include high tensile strength, high resistance to creep, cut-through, abrasion, solvents and chemicals. It has high dielectric strength which makes it an ideal insulating material for use with high voltage. Polyimide film will resist radiation and ultraviolet light. It is flame retardant rated as well.
