HEATFLEX KAPTON™ HEATERS

APPLICATION ADVANTAGES Kapton Heaters

Continuous operation from -320°F to 400°F.
High watt densities possible due to a minimum of insulation between element and surface to be heated.
Extremely lightweight.
Very thin profile.
High tensile strength and tear resistance.
Excellent dimensional stability; especially in small heaters.
Extremely low outgassing.
Radiation resistant.
Resists most solvents and chemicals including oil.
Fungus resistant.
Transparent.
Conforms to sharp bends and radii.

INSULATION CHARACTERISTICS

Kapton™ is a clear amber colored polyimide film. Kelvin's HEATFLEX Kapton™ heaters have an overall thickness of .007". This consists of a top and bottom layer of Kapton™ , each with a thickness of .002", corresponding layers of adhesive, each at .001" element.

ELEMENT SELECTION

The standard elements for HEATFLEX Kapton™ heaters are the same etched circuits used in the silicone rubber heaters. Standard circuit thickness is .001" except in cases of high resistance density when .0005" circuits must be used.
