Kapton is a thin, semitransparent material with excellent dielectric strength. Kapton heaters are ideal for applications with space and weight limitations, or where the heater will be exposed to vacuum, oil, or chemicals.

- FEP internal adhesive for use to 200°C
- UL component recognition available
- Suitable for vacuum environments (NASA-RP-1061)
- NASA approved materials for space applications(S-311-P-079)
- Resistant to most chemicals: acids, solvents, bases (except NaOH)
- Radiation resistant to 10⁶ rads if built with polyimide-insulated leads (custom option)
- Can be made in very small sizes
- Fluid immersible models available (not standard)

AP heaters are a high performance alternative to Minco’s standard Kapton heaters, allowing higher temperatures and watt densities. They must be factory mounted or clamped to heat sinks.

- Uniform heating to 260°C (500°F)
- Exceptional temperature uniformity when designed with a heat-profiled foil pattern
- Thin, flexible etched-foil construction
- Available in round, rectangular, and irregular shapes
- Can be factory bonded to mating parts with no clamping hardware!
- Power ratings to 80 watts per square inch
- Resistant to most chemicals
- Optional built-in temperature sensors
- Custom designs only

Silicone rubber is a rugged, flexible elastomer material with excellent temperature properties. It is most suited to larger heaters and industrial applications.

- High temperature capability to 235°C (455°F)
- UL component recognition available
- Can be factory vulcanized to metal parts without adhesive
- Resistant to many chemicals
- Not suitable for radiation, vacuum, or prolonged exposure to oil
- Most economical in large sizes

These heaters have a wire element instead of foil. They are more economical in larger sizes, but are thicker and have reduced watt densities.

- Rugged
- Easy to install
- Uniform heating to 220°C (428°F)
- Lengths to 70" (1.8 m)
- Economical in large sizes
- Withstand repeated flexing
- Mount to flat or curved surfaces
- TÜV and UL component recognition marking are standard
- 2.5, 5, 10, 15 watts/in² at 120 or 240 VAC
- Lower leakage current due to capacitive coupling (may be important for large heaters used in medical applications)

These heaters consist of an etched foil element sandwiched between layers of mica. An organic material binds the layers together and burns off during initial warmup. Installed by clamping to heat sinks, mica Thermofoil heaters provide the ultimate temperature and wattage capability for fast warmup.

- Extremely high temperature capability to 600°C (1112°F)
- Power rated to 110 watts per square inch — 50% higher than conventional mica strip heaters
- Can be factory formed to curves
- Clamp directly to heat sink for exceptional heat transfer
- Suitable for vacuum use after organic binder is burned off in initial power-up

Integrated heater/sensors are the ideal solution for many temperature control problems. Combining an etched foil heating element with an accurate, stable RTD or thermistor sensor in a single package provides a reliable system with reduced parts count and simplified installation.

Minco standard heater/sensors have the sensor element located in a non-heating area to measure the heat sink temperature — not the heating element temperature. The result is a more accurate reading and better control. Precise location of the sensor ensures consistent readings every time.

These heaters are ideal for use with the CT325 Miniature DC Controller.
