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
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:
Oil and solvent 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 customflexible 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.

National Plastic Heater supplies kapton polyimide heaters for many other different
applications such as industrial catering, battery warming, environmental control
or electronics (particularly telecommunications), laboratory equipment and anti-condensation.
The uses for polyimide heaters are infinite as they can suit any application requiring
surface heating up to 200°C. Their suitability for arduous conditions has been proven
in applications from polar expedition to space exploration. We are the final frontier
in polyimide heaters!
TEMPERATURE CONTROL FOR KAPTON (POLYIMIDE) FLEXIBLE HEATERS:
NPH Kapton heaters can be supplied with factory fitted sensors and switches to suit
