Kapton® polyimide film is chemically imperious to almost anything except strong alkali solutions. It is often considered the closest thing to a bombproof XRF window film due to its incredible strength and heat resistance to over 300°C (572° F). The phosphate-based surface coating improves its handling characteristics.
