What is the heat resistance of circular light diffuser film? Circular light diffuser film is designed for use in environments below 85C/185F. At higher temperatures, the matte surface could yellow, or lose some of its ink adhesion properties. At really high temperatures (above 150C), it begins to lose its orientation; it will become wavy and shrink.
