Kapton and silicone rubber 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 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).
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 custom flexible 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 m). Kapton® 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.
Flexible heat tapes -The flexible design and high temperature capability of our
Heating Tapes and Cords provides an ideal solution. Heating tapes and cords can be
used on any surface or body requiring fast and efficient direct contact heating,
up to temperatures of 1400°F (760°C).
Heating element is laminated between two layers of 23 mil and two layers of
Fiberglass reinforced silicone rubber
Nominal silicone rubber density of 26 oz/yd2 (881 grams/m2) per layer
Attached adjustable dual set-point NEMA 7 temperature controller with power
cord 6 feet (1.8m) long. One set-point is set at a high temperature limit and connected
to a red indicator light.
Blanket leads 6 feet (1.8m) long for NEMA7 controller; 1 foot (0.3M) without
Leads from blanket to controller are enclosed in a liquid tight conduit
400 degrees F (204°C) maximum exposure temperature on heating surface
Moisture and chemical resistant
Silicone rubber drum and pail heaters -Provide practical, efficient means of freeze
protection, viscosity control and maintenance of materials at elevated temperatures.
A variety of standard sizes are combined with availability of configure-to-order
designs to meet a variety of applications.
Tote Tank/IBC Heaters – Speed up the flow of products like honey, molasses, lube
oil, biofuel, etc. stored in bulk containers. Safely heat: Does not contaminate or
scorch your product. Warm bulk tote tank contents at a required temperature, Viscosity
control, Freeze protection, Thermal mixing Temperature maintenance, Biofuel / Biodiesel.
Hoppers and Dip Tanks -NPH Hopper Surface Heating Systems maintain elevated temperatures
above moisture and acid dew points using a proven combination of:
Modular hopper surface heaters
Flexible heating tapes for throats, poke tubes, and manways
Temperature control and installation hardware
Laboratory Heating Tapes -Flexible, multi-purpose heater ideal for wrapping around
graduated cylinders, beakers, distillers, flasks, and other laboratory equipment.
Heating Mantles - Laboratory Heating Mantles offer uniform heat distribution for
round-bottom flasks. Whether the need is a self-standing mantle, a mantle to fit
in a basket ring stand, or a full coverage zippered mantle, NPH Heating Mantles provides
Heat Trace Cable -Heating cable is also referred to as heating tape and heat trace
cable amongst the industry. Heating cable is used for a wide range of applications
including pipe tracing, freeze protection, viscosity control, temperature process
maintenance, roof and gutter, and much more. NPH also offers a true heating tape
that is much more flexible and provides a more rapid thermal response.
Self-regulating or constant-wattage heating cable
