This type of heater can have a distributed wattage where constant temperature is required across the entire surface. It has a pressure-sensitiive adhesive to facilitate mounting. This adhesive is strong and not easily removed after the heater has been installed.
Polyester heaters are best suited to an application where a large surface requires heat of 200 degress F or less. The limitation is watt density.
