What is the operating temperature range for the polarizing film?

The polarizing film XP42 contains an iodine dye to obtain its light polarizing function. If the temperature of the film exceeds 80°C the polarizing component will be damaged. For applications up to approx. 100°C we recommend the polarizing film type XP40HT as this contains a modified polarizing component with improved heat resistance.
