Film heaters are extremely thin planar heaters with a thickness of .02″ (0.4 mm) or less. Since this heater use a polyimide sheet, it has superior resistance to chemicals.

Thanks to our unique manufacturing method, it’s also siloxane-free. Use this heater with peace of mind in environments where there are concerns that siloxane may have a detrimental effect on electrical devices, such as in clean rooms or sealed control boxes.

The heater can also be modified for complex shapes, such as holes, notches, or curls. We’ll propose the best heater specifications to each customer that is optimum for how our customers plan to use it.
