Polyimide Thermofoil Heaters
Thin, exible heating solutions from -200 to 200°C
Overview
• Polyimide (Kapton™) is a thin, semitransparent material
with excellent dielectric strength. Polyimide Thermofoil™
heaters are ideal for applications with space and weight
limitations, or where the heater will be exposed to
vacuum, oil, or chemicals.
• The lightweight heater has less thermal mass to improve
thermal response
• The thin profile with nearly infinite custom X-Y geometry
design options allows you to apply heat where it’s needed,
reducing operating costs
• Etched-foil heating technology provides fast and efficient
thermal transfer
• Customized options (i.e. SMT components, flex leads and
connectors) offer turnkey solutions to drastically reduce
assembly time and increase productivity
• Custom profiling gives uniform thermal performance
of the heating output to improve processing yields and
productivity
• UL and TUV component recognition available
• Suitable for vacuum environments (NASA-RP-1061)
• NASA approved materials for space applications
(S-311-P-079)
• Resistant to most chemicals: acids and solvents
• Radiation resistant to 106 rads if built with polyimide-
insulated leadwire (custom option)
• Very small sizes available
• Fluid immersible designs available (not standard)
• Optional built-in temperature sensors
Mounting Methods
• #12 PSA with aluminum backing
• Acrylic PSA with or without aluminum backing
• #15 epoxy
• BM3 shrink band
• Stretch tape
• Mechanical clamping
Typical applications
• Medical diagnostic instruments and analyzers
• Maintain warmth of satellite components
• Protect aircraft electronic and mechanical devices against
cold at high altitudes
• Stabilize optoelectronic components
• Test or simulate integrated circuits
• Enable cold weather operation of outdoor electronics such
as card readers, LCDs or ruggedized laptops
• Maintain constant temperature in analytic test equipment
