Wire-Wound Silicone
Silicone rubber heaters provide dependable performance under rigorous conditions. Ambient temperatures down to –80°F and up to 500°F do not diminish performance. These heaters can be designed and fabricated in many configurations to fit the size and shape of almost any application requirements.
Features
- Long life, high reliability
- Versatile configurations – flexible for flat or curved installations
- Able to withstand extreme ambient temperatures
Construction
The excellent dielectric properties of silicone rubber and the strength of fiberglass combine to produce a unique heater. First, 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 used 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.
If you have any questions regarding wire-wound silicone heaters, please call us at 866-685-4443, send us an e-mail, or fill out a contact form.
Note: These heaters take up to 1–2 weeks to ship.
