Kapton® flexible heaters offer superior tensile strength and tear resistance, with precision heat distribution. They are ideal for extreme temperature environments, from -319°F to +392°F (-195°C to +200°C). Heaters are in stock standard at 0.0007" (0.2mm) thick and up to 20"x26" (.508m x .660m) areas. Watt density is 5W/in² (0.8W/cm²) standard, with units available to 50W/in² (7.8W/cm²). Kapton® is an organic polymer with very high dielectric capabilities, while providing superior resistance to most solvents, oils, even radiation. With low out gassing, these heaters are useful in vacuum environments. Etched foil heating elements, with 12" (305mm) long Kapton or Teflon® leads, are standard. Silicone leads, as well as custom lengths, cord and plug sets available.

Being transparent, Kapton® film also allows easy visual inspection on the internal structures. Pressure-sensitive adhesive (PSA) backing surface is not standard, but NPH will customize your Kapton® heaters with special adhesives or mounting holes, as the application requires. Mechanical fasteners such as hooks, grommets, spring-loaded latches, snaps and Velcro® patches are also available. Minimum radius flexibility 1/32" (0.88mm) standard with weight of 1 1/2oz/ft² (0.05g/cm²).

Bespoke silicone rubber heaters consist of many layers of silicone rubber sheets that are bonded together through heat and high pressure. A fiberglass grid (which is visible on the surface) reinforces the silicone rubber sheets. It is possible to make the surface of the heaters smooth (i.e. make the grid invisible) by covering the fiberglass with a thin layer of silicone. A uniformly spiraled resistance wire web that covers the entire surface of the heater is embedded within the layers of silicone rubber. This web could be designed such that holes and cut-outs are incorporated on the heater. When silicone rubber heaters are made with a pressure sensitive adhesive backing, a thin layer of aluminum is added prior to the adhesive layer, in order to improve heat transfer and maintain its uniformity. This construction makes silicone rubber heaters an ideal solution to the requirements of many low and medium temperature applications, which do not conform to the standard shapes, sizes and dimensions of band, strip, cartridge, tubular and coil heaters.

Wire Wound-Custom Silicone Rubber Heaters
Using evenly spaced resistance wires laminated between sheets of silicone, wire wound silicone rubber heater mats are ideal for prototyping or problem solving applications. Manufactured to customer specifications they can be made in a limitless range of shapes and sizes. High flexibility can be obtained using tough, robust silicone materials which are finding ever increasing applications in the industry. Silicone's wide temperature range, tolerance of -60 to +230 °C and superb electrical properties give it a distinct advantage over other forms of heating.

Etched Foil-Silicone Rubber Heaters
Computer designed chemically etched foil tracks are laminated between thin sheets of silicone to give precise even heating. Suitable for both low and high volume production etched foil heaters have rapid heat up properties with precise temperature control. Heating solutions are available in a limitless range of etch foil heaters to customer specification for multiple industries. Silicone's wide temperature range, tolerance of -60 to 230°C and superb electrical properties give it a distinct advantage over other forms of heating.
