CUSTOM SILICONE RUBBER AND KAPTON HEATERS - DESCRIPTION
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).
Custom 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.
Custom Silicone Rubber Heaters- Wire Wound
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.
Silicone Rubber Heaters – Etched Foil
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.
Silicone rubber and custom kapton heaters are extremely versatile and operate efficiently
in many environments. Some distinct advantages of custom silicone rubber and kapton
flexible heaters are:
Oil and solvent resistance,
Outdoor exposure ,
Extremely thin profiles,
Conform to almost any shape.
All silicone rubber and kapton heaters are built to order, but rush delivery (3-5
days) is available. In most cases, NPH can deliver custom silicone rubber and kapton
flexible heaters within 10-15 Days. All NPH flexible heaters are available with custom
design modification. Custom designs are welcome. Please contact us with your requirements.
Custom Silicone Rubber and Kapton 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® 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

Applications requiring a flexible shape or design
National Plastic Heater supplies customsilicone rubber and kapton flexible heaters
for many 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!
THERMAL OR TEMPERATURE CONTROL FOR CUSTOM SILICONE RUBBER HEATERS:
NPH silicone rubber heaters can be supplied with factory fitted sensors and switches
to suit all types of instrumentation. Available from stock are PT100’s, J, K and
T type thermocouples, bi-metal thermostats and thermal fuses. We also fit customer
specified thermistors and other resistance temperature devices as well as extruded
pockets for customers to fit their own sensors. Separate mechanical or digital thermostats
can be supplied for process control.
