Our film heater is made from
etched foil element as its middle layer and polyamide film (Kapton film), polyester(PET
film) film, PTFE film (Teflon film) as its insulated surfaces. The
film heaters are able to operate
at very high watt densities, this is due to the large surface area covered by
the foil circuit. The flat foil circuit also gives excellent uniformity and
faster heat transfer resulting in longer heater life in high power applications.
Also the excellent circuit pattern allows the design of complex heat
distribution patterns and an
exceptionally uniform heat output
with different watt densities within the heater area.
Polyamide film is thin lightweight organic polymer, which provides high dielectric strength, excellent tensile strength, tear resistance and dimensional stability, is an ideal material for applications requiring low outgassing or resistance to radiation, chemicals and solvents. Its operating temperature range is from -195℃ to +270℃.
Polyester film is low cost
alternative to polyamide. Polyester is suitable for low temperature applications up to 120℃.
installation, the pressure sensitive adhesive (PSA) is
available as an option on film heaters for operating temperature <150℃. For
operating temperature>150℃,the heaters can be mounted on site by RTV
silicone rubber adhesive or epoxy adhesive, also mechanically clamped.
film heaters are available in a variety of shapes, sizes, and wattages.
Operating Temperature Range: -200 °C to 260°C for Polyimide Heaters type; Maximum operating temperature for heaters with pressure sensitive adhesive (PSA) is 120°C; Maximum operating temperature for PET heaters is 120 °C.
