Kapton (Polyimide) Flexible Heaters
KAPTON (POLYIMIDE) FLEXIBLE HEATERS-PRODUCT DESCRIPTION
Polyimide (Kapton™) is a semitransparent, flexible, thin material, ideally suited for the manufacture of etch foil heater mats. With its low thermal mass, superb electrical insulating properties and excellent resistance to most chemicals, it allows high power densities with fast and efficient thermal transfer. Being thin and lightweight with a wide temperature range Kapton (polyimide) flexible heaters have a distinct advantage over other forms of heating elements. Where fast response, chemical resistance and a low profile is required kapton (polyimide) flexible heaters offer the ideal solution.
Kapton (polyimide) and silicone rubber heaters are extremely versatile and operate efficiently in many environments. Some distinct advantages of kapton (polyimide) and silicone rubber heaters are:
- Moisture resistance
- Oil and solvent resistance
- Chemical resistance
- Outdoor exposure
- Extremely thin profiles
- Conform to almost any shape
All silicone rubber and kapton (polyimide) heaters are built to order, but rush delivery is available. In most cases, NPH can deliver custom silicone rubber and kapton (polyimide) heaters within 72-96 hours. All NPH flexible heaters are available with custom design modification. Custom designs are welcome. Please contact us with your requirements.
Kapton (Polyimide) Flexible Heaters - 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 kapton heater units available to 50W/in² (7.8W/cm²). Kapton® (polyimide) 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. Kapton 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).
Kapton® (Polyimide) Flexible Heaters - The particular application conditions of aerospace, medical, composite fabrication, optical equipment and computers often require flexible heating elements. NPH offers a wide assortment of in-stock and custom flexible heaters in kapton® (polyimide) and silicone rubber materials to suit most any of these needs. Silicone Rubber heaters permit composite bonding and curing, as well as repair and fabrication operations. Equal length circuits and a cool tab are provided, while a fiberglass reinforced heater cover means long service life and increased durability. Standard watt density is 5W/in2 (0.8W/cm2). All standard heaters are UL Recognized. Many sizes in stock from 6” x 6” to 20” x 20” (152.4 mm x 152.4 mm to .508 m x .508 m). Kapton® (polyimide) flexible heaters offer superior tensile strength and tear resistance, with precision heat distribution. They are also ideal for applications with extreme temperature environments, -319°F to 392°F (-195°C to 200°C). Heaters in stock standard at 0.007” (0.2 mm) thick and up to 20” x 26” (.508 m x .660 m) area. Watt density is 5W/in2 (0.8W/cm2 ) standard.
