 Silicone Heater Element
Silicone rubber heater can be made with etched foil heating elements or wire wound heating elements.
A)Etched Foil Silicone Rubber Heaters
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 silicone rubber heaters:
·Higher watt densities
·Distributed wattages
·Elimination of edge loss compensation
·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
B)Wire Wound Silicone Rubber Heaters
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
 Dual Voltage, Zoning and Three Phase
Due to the flexibility in circuit design of silicone rubber heaters, multiple heating circuits can be designed to accommodate dual voltage and multiple zones. On dual voltage heaters, three leads, including a common in a different color, are provided for wiring the heater in series for the higher voltage and parallel for the lower voltage. 120/240 Vac or 240/480 Vac can be achieved. Multiple circuit areas can be zoned to achieve different heating effects. Three-phase circuits can also be designed for high current applications.
Water-proof
We have developed leak tight silicone rubber heaters which can be permanently immersed into water. This is very useful for high humidity environment or fluid heating where conventional immersion heaters can't be used due to space or mounting limit. The applicable fluid includes some corrosive chemical solution. For example, our silicone rubber heaters have been used for SCR (Selective Catalytic Reduction) tank Adblue heating for exhaust gas control of diesel vehicles. Please consult us for chemical compatibility if you have similar demand. And our silicone rubber heaters have tested IP68 and passed it
