Polyimide (Kapton™) is a thin, semitransparent material with excellent dielectric strength. Polyimide WA Thermofoil™ heaters are ideal for applications with space and weight limitations, or where the heater will be exposed to vacuum, oil, or chemicals. Features: Thin, lightweight heaters allow you to apply heat where it’s needed, reducing operating costs Etched-foil heating technology provides fast and efficient thermal transfer WA internal adhesive for use to 150°C (302°F) Acrylic pressure sensitive mounting adhesive (PSA) UL component recognition available Suitable for vacuum environments (NASA-RP-1061) Resistant to most chemicals: acids and solvents Radiation resistant to 106 rads if built with polyimide-insulated leadwire (custom option) 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
