Minco polyamide flexible thermal heater

In volatile thermal environments — like deep outer space — you can’t afford to have critical systems fail. It’s in these cannot-fail situations where our proven design expertise shines through best. From powerful heaters designed to prevent satellites from freezing billions of miles from Earth, to precise temperature control in medical devices, our team has the experience to bring your design ideas to life. Minco flexible heaters can introduce new design versatility to creatively solve a variety of thermal management challenges — from more consistent environment stabilization to faster thermal cycling.


A flexible heater is a thin electrically resistive core laminated between layers of flexible insulation.  Flexible heaters can be designed with custom shapes to be installed exactly where a surface needs heating.  The design of the heaters can  be further custom profiled to put more heat in areas where heat loss is greatest. 


Minco flexible heaters are technologically divided by the type of resistive core: Thermofoil™ heaters with etched-foil heating elements, Thermal-Clear heaters with wire heating elements or SmartHeat SLT™ thin-film heaters with a carbon-silicone matrix for heating.  A Thermofoil heater is a flexible heater consisting of an etched-foil resistive heating element laminated between layers of flexible insulation.   The heaters can be designed with custom shapes to be placed or bonded exactly where a surface needs to be heated.  Multiple options are available for integration of sensors and other electrical components.

Thermofoil heaters can operate in a wide range of environments and temperatures by using an appropriate electrical insulation in the product construction.  Standard insulations include silicone rubber, polyimide, PTFE, and mica.

A Thermal-Clear heater is a flexible heater consisting of patterned micro-thin wire resistive heating element laminated between optically clear adhesive and polyester insulation.  The construction of the Thermal-Clear heater allows for heating to be applied to surface while still allowing light to pass through.  Custom shapes, wire sensing elements, and profiled heating patterns are available.

A SmartHeat SLT™ thin-film heater is flexible heater consisting of a self-limiting carbon-silicone heating matrix with etched-foil copper conductors laminated between polyimide insulation.  The patented polymer core is temperature self-limiting which allows for operation at a designed uniform temperature without the need for external sensors or controllers. Custom shape options are available.


  • Precise heating: Put the heat where you need it.  The thin construction provides close coupling between the heater element and the heat sink.  Profiled heating can be used to put high-density power in areas where heat loss is greater.
  • Faster warmup and longer life:  Flexible heaters are designed to put the heating element as close to the surface to be heated as possible.  This allows the heating element to operate at lower temperature compared to other technologies; allowing for longer operational life.
  • Space and weight savings.  Flexible heaters are constructed with thin materials which delivers heat where it is needed while minimizing size and weight.
  • Custom tailored shapes to put heat where it is needed and reduce costs by optimizing for the required size and design to do the job.
  • In-house integration with sensor, controller, flexible-circuits, and other electrical components.  Total assembly cost saving and optimal performance in a heating system can be achieved by Minco integrating components with a flexible heater.
  • Complete assembly integration:  cost and performance targets can be achieved by taking advantage of Minco’s expertise in factory lamination and installation of heaters on to mating heat sinks.
