Kapton heater

What is a Kapton heater?

Kapton heaters, also known as polyimide heaters, are made from a polyimide film developed by DuPont. Kapton heaters provide the slimmest profile of all flexible heaters, offer precise heat distribution and excellent tensile strength. They work well in extreme heat environments or small spaces.

How do Kapton heaters work??

Kapton heaters are constructed with an etched foil element of 0,0005 ”or 0.0001” of thickness, which is encapsulated between two layers of polyimide film and FEP adhesive 0,001 ”. These flexible heaters are available in a variety of shapes, sizes and powers. The nominal powers are 2.5, 5 o 10W / in2 a 115 o 28 V. Its slim, lightweight profile combined with high watt density makes it possible to achieve precise heat distribution at a low operating cost..

What are the operating temperatures of Kapton heaters??

Kapton heaters are excellent for extreme temperature environments. They can maintain temperatures of -40 ° C a 180 ° C. They are also self-extinguishing and can maintain their original shape regardless of temperature exposure..

Kapton Heaters Installation Instructions

Proper mounting of the heaters will ensure good heat transfer between the heater and
the surface that is being heated (heat sink), which in turn will save energy, will avoid dangers /
damage and extend the life of the heater. See the Chromalox design guide
for temperature limits, electrical and operational.

Installation with pre-applied PSA:
1. The heat sink must be clean of oil, fat and
tierra. It is recommended to clean with alcohol or acetone.
2. Pre-place the heater on the heat sink and then,
without touching the adhesive, remove the mold release
cover in a corner.
3. With uniform pressure, starting from the corner, slowly
press heater / adhesive against the heatsink while removing the release cover.
4. Avoid air gaps which can cause hot spots resulting in
heater failure.
5. For better adhesion, roll or press from inside
just.
6. Make sure the heater is properly controlled so as not to exceed the maximum temperature rating.
Installation with customer-applied PSA:
1. The heat sink must be clean of oil, fat and
tierra. It is recommended to clean with alcohol or acetone.
2. Place the heater over the release liner and cut leaving approximately one edge of 1/2 ”
3. Trim the PSA at the same level as the heater avoiding cutting or damaging the heater.
4. Pre-place the heater on the heat sink and then,
without touching the adhesive, remove the mold release
cover in a corner.
5. With uniform pressure, starting from the core, slowly
press heater / adhesive against the heatsink while removing the release cover.
6. Avoid air gaps which can cause hot spots resulting in
heater failure.
7. For better adhesion, roll or press from inside
just.
8.Make sure the heater is properly controlled so as not to exceed the maximum temperature rating.
