Temperature Sensors and Switches for Silicone Rubber Heaters
NPH silicone 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.
Specialist Materials and Approvals
As well as the large variety of stocked silicone materials available, NPH can manufacture
heaters in specialist silicones to customer requirement such as colour, thickness
and Low Smoke/Low Toxicity. We are certified to manufacture silicone heater mats
with UL, CSA or VDE approval, which simplifies full approval for the finished assembly.
Supply Cable and Connectors
NPH standard termination is via single leads or multi-core silicone cables. These
can be terminated with connectors by major manufacturers such as Amp and Molex. Other
types of cable as well as spiral wrap and heatshrink sleevings are available on request.
Integral Foam Insulation
To provide higher efficiency during heating, NPH flexible silicone heater mats can
be thermally insulated with a closed cell silicone foam insulation vulcanized to
one face. Many thicknesses are available from stock, as well as specialist types
such as flame retardant that can be supplied on request.
Brand Marking for OEM and Large Production Run Customers
Products are marked with identification and batch numbers giving full manufacturing
traceability. Branding with the client details and logo is available upon request.
Silicone rubber heaters are extremely versatile and operate efficiently in many environments. Some
distinct advantages of silicone rubber heaters are:
Oil and solvent resistance,
Outdoor exposure ,
Extremely thin profiles,
Conform to almost any shape.
All silicone rubber heaters are built to order, but rush delivery (3-5 Days) is available.
In most cases, NPH can deliver custom silicone rubber heaters within 10-14 days.
All NPH flexible heaters are available with custom design modification. Custom designs
are welcome. Please contact us with your requirements.
Silicone 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).
Heating of Electronic Components- ATM's and Photocopiers
Heating of Aerospace Instrumentation-Satellites and Spacecraft

Applications requiring a flexible shape or design
National Plastic Heater supplies silicone rubber 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!
