Etched Foil Silicone Rubber Heaters

The etched element provides superior heat transfer and exceptionally uniform heat output, resulting in a faster warm-up cycle and longer life. These flexible heaters operate in ambient temperatures from -80°F to 500°F.

Advantages over wire wound silicone rubber heaters:
  • Higher watt densities
  • Distributed wattages
  • Greater element area over heater sheath
  • Complex heat distribution with a rating of about 200°C (392°F)
  • Economical mass production
  • Reproduction of complex circuits

Wire Wound Silicone Rubber Heaters

A fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass, producing a strong, flexible heating element. Electronically-controlled precision winding equipment ensures consistency. Circuits are then hand-wound on permanent tooling, providing repeatability of resistance and pattern. Parallel circuits are utilized where possible, permitting continued operation should a single circuit be damaged.

Wire wound advantages over etched foil element:
  • Faster turnaround time on prototype designs
  • Lower engineering cost
  • More economical pricing at lower quantities
