Flexible Solutions for Accurate Heating
Thermofoil™ flexible heaters provide accurate, reliable and rapid heat transfer to your application. Our heaters are thin and flexible consisting of an etched-foil resistive element laminated between layers of flexible insulation.
When you need a flexible heater to perfectly fit your application, Minco’s engineering and technical expertise will help you design the optimal heating solution. Size and shape possibilities are virtually limitless. Download the Flexible Heaters Design Guide or contact us at InTec Alliance for collaboration on your project.
Integration and Value Add
Minco can integrate flexible heaters with temperature sensors, flex circuits, controllers and other electronics to provide a complete heating solution. We can also laminate, vulcanize or clamp the heater assembly to heatsinks to provide a comprehensive turnkey thermal solution.
Polyimide (Kapton®) Thermofoil™ Heaters

Polyimide Thermofoil flexible heaters, or Kapton heaters, are ideal for applications with space and weight limitations, or where the heater will be exposed to vacuum, oil, or chemicals. These thin, flexible heaters are rugged, accurate and reliable.
Benefits of Polyimide Flexible Heaters:
- Thin, lightweight heaters allow you to apply heat where it’s needed, reducing operating costs
- Etched-foil heating technology provides fast and efficient thermal transfer for increased throughput
- Customized options (i.e. SMT components, flex leads and connectors) offer turnkey solutions to drastically reduce assembly time and increase productivity
- Custom profiling gives uniform thermal performance of the heating output to improve processing yields and productivity
Silicone Rubber Heaters (foil)
Silicone rubber Thermofoil™ heaters have etched-foil elements and are most suited to large-size, industrial and ruggedized applications. Silicone rubber is a rugged, flexible elastomer material with excellent temperature properties.
Benefits of Silicone Rubber Heaters:
- Rugged construction provides high reliability in a wide range of heating applications and reduces need for field repair and replacement
- Optional custom profiled heat density creates a uniform heat sink temperature which can improve processing yields
- Factory vulcanization and high temperature capability allows higher wattage levels for faster processing
Features of Silicone Rubber Heaters:
- 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
