10. Minimum Curve Semidiameter: (0.8mm)

 Polyimide is an organic polymer with very high dielectric 
capability, thin profileand low thermal mass, while providing superior 
resistance to most solvents, oils,and radiation. In connection with 
these features, kapton heaters are very ideal for applications:
 With space and weight limitation
 The heater will be exposed to chemical or oil
 In vacuum environments due to low outgassing
 Fast and precise heating

Complicated heating profiles(e.g. Multi-zone heater) for lasers and 
precision instruments can be easily realized.


Being transparent, Kapto film also allows easy visual inspection on the internal strutures. Pressure-sensitive adhesive(3M) backing surface is standard, but special adhesive or mounting holes can be customized 
pre customer requirement. Special cord and plug sets available.

Specification of Polyimide Heater

Why Kapton

  • Heating for very small sizes
  • Very thin
  • High dielectric strength
  • Flexible circuit design
  • Superior tensile strength and tear resistance
  • Resistant to radiation and most solvents
  • Better choice far high watt density heaters (those over 5 watts/in2). Also used for watt densities of 5 or less.
  • Excellent choice for heaters that require multi-zoned wattages or heaters that have many holes and/or cutouts.
  • May provide an economic advantage for high volume applications.
