Durex Industries manufactures polyimide heating elements constructed of a thin, etched-foil circuit laminated between two lightweight polyimide films that provide high dielectric strength, superior chemical resistance and low outgas characteristics. Polyimide Heater Design Advantages In addition to being lightweight, polyimide flexible heaters also provide the following advantages: Precise heat distribution and zoning with intricate etched foil heating elements. Ultra-thin profile at a typical 0.007” (0.18mm) value that promotes efficient heat transfer to parts Very low outgassing for applications that do not tolerate contamination High solvent and chemical resistivity Ideal for extreme temperature environments such as vacuum and space applications. Semi-Transparent film allows easy visual inspection of parts and internal structures Considerations when Selecting a Polyimide Heater A polyimide heater can be an excellent choice when the following are applicable: Silicone rubber or other flexible layered materials cannot be used High power density (watt density) is required Chemical exposure Outgassing may cause contamination, fogging or other undesirable issues Exposure to radiation such as in satellites Use in vacuums Precision contours such as holes, notches, cutouts, etc. are required Integrated sensors, thermal fuses, connectors, etc. are required Polyimide Heater Assemblies and Heated Parts for OEMs Heater assemblies and heated parts are perfect for OEMs looking for a one-stop shop who can provide ready-to-install heater solutions for their equipment. Durex has years of experience working with OEMs to develop creative solutions that meet the complexity of today’s equipment requirements. It can be as simple as designing custom distributed wattage heat profiles on the polyimide heater. Or it can be as complex as adding integrated sensors, fuses, harnesses, connectors, and including factory bonding to the part. Customers then just pull the parts out of the box and install the assembly into their equipment providing a “plug and play” solution.

By selecting proper materials, including the release agent, you can promote a strong bond and effective heat transfer. Clamping Polyimide heaters can also be clamped to their heating surface. A pressure plate is then fastened in place. To ensure even distribution of heat, and to protect the polyimide heater, a pressure pad or insulation layer is advised. The work surface should be free of any debris, dirt, chemicals, bumps, or grooves. This will protect the polyimide heater as well as prevent overheating. Self-Fusing Tape When mounting to a smooth cylindrical surface, polyimide heaters can be mounted with self-fusing tape. This will provide a safe operation and even transfer of heat. Polyimide Heater Control Options For temperature control on polyimide heaters, Durex recommends a resistance temperature detector (RTD) or thermocouple. Temperature sensors are mounted to the surface of the heater and send a resistance measurement to an external temperature controller that cycles the heater at a set temperature.
