Kapton Heater

Lead Wires
Kapton heaters can have Teflon, Silicone or Kapton insulated stranded lead wires that are attached to the weld tab of the resistive circuit. The attachments are covered with high temperature epoxy. The gauge and amps of the lead wires are as follows:

Gauge Amps
30 2
26 4
24 6
20 12

 

Attachment Methods

  • The most common method to attach a Kapton heater to the surface of an application is through pressure sensitive adhesive (PSA), which is adequate for 250°F continuous (days, weeks) and 350°F intermittent (minutes, hours) operations.
  • Kapton heaters could be clamped between surfaces.
  • Self-fusing tape could be utilized to attach Kapton heaters to cylindrical surfaces by wrapping self-fusing tape around the Kapton heater.

Temperature Sensors and Thermostats

Kapton heaters can accommodate thermostats, thermal cut-offs, thermal fuses, external "J" type thermocouples and RTDs. Each of these temperature sensing and controlling devices has a specific temperature range and maximum amperage capability; the factory should be consulted for their availability.
