Etched Foil Silicone Rubber Heaters
Our designers use custom software to calculate the configuration of the heating element, given the voltage, wattage and resistance. Nickel alloy foil is acid-etched in the resulting pattern. The foil is then vulcanized to the silicone rubber sheath material.
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
- Distributed wattage
- Complex heat distribution
- Edge loss compensation
- Accurate reproduction of complex circuits
- Greater element area over heater sheath
Wire Wound Silicone Rubber Heater
A fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass twine, 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. When the heating element is positioned, a second layer of silicone rubber is laid over the wire.
The layers are then vulcanized to permanently position the circuits.
Wire wound advantages over etched foil element:
- Faster turnaround time on prototype designs
- Lower engineering cost
- More economical pricing at lower quantities
