Flexible Silicone Drum Heating Strip can be made with etched foil heating elements or wire wound heating elements.
a)Etched Foil Flexible Silicone Drum Heating Strip
The etched element provides superior heat transfer and exceptionally uniform heat output, which results in a faster warm-up cycle and longer life. The heaters operate in ambient temperatures from -80°F to 500°F.
Advantages over Wire Wound Flexible Silicone Drum Heating Strip:
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 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.
Using these versatile and flexible heaters, the ability to apply heat exactly where required is limited only by imagination — and a maximum continuous operating temperature of about 200°C
