Flexible Silicon Rubber Heater Options

OverviewOptionsApplicationsTech Specs

Etched Foil:

  • Etched foil provides options for variable watt density and heat patterns.
  • Etching circuits is an efficient method for manufacturing in high quantities.
  • Foil thickness ranges from .0005″ to .004″ depending on your required resistance. 
  • Different material types can be used depending on the heater resistance, and because the etched circuit element is flat foil, the element itself can cover up to 80% of the heater area.
  • Etched designs are excellent for applications requiring watt densities greater than 5 watts/in2.
  • Excellent choice for heaters that require multi-zoned wattages or heaters that have many holes and/or cutouts.
  • Offers excellent circuit repeatability.
  • Initial one time artwork and die cutting charges may apply.
  • May not be suitable for some high resistance heaters.

 Wire Wound: 

  • Wire wound silicone heaters start with one to five strands of machine-wound resistance wire
    • The element is wound around dedicated tooling and transferred to a layer of silicone rubber.
    • A final layer of silicone rubber is then placed over the element to complete this heater.
    • Our technicians work with various material combinations specifically chosen based on your desired resistance and flexibility requirements
  • Provides excellent repeatability for short run orders.
  • Better choice for flexing applications.
  • Adapts to contoured surfaces with relative ease.
  • Advantages in high resistance applications and heater sizes not lending themselves to the etching process.
  • Prototypes can be delivered quickly at minimal cost.

 Sensors and Control Options: 

  • Flexible heaters can be easily configured with Thermistors, RTDs, Thermocouples, or Automatically Resetting Thermostats.
  • Sensing options can be incorporated into the heater design

 Attachment Methods: 

  • Heaters can be supplied with Pressure Sensitive Adhesive for attachment at customer location
  • Heaters can be vulcanized to many metal and plastic parts.  This method provides intimate contact and superior heat transfer form the heater to the part being heated.
  • Snaps, Boot Hooks, and Grommets can be incorporated into the design for easy attachment to almost part configuration
  • Heaters can be formed to various shapes to aid attachment
