Fax Back Data Sheet

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 types of configurations to fit the size and shape required in your application.

  • Long life
  • High reliability
  • Versatile configurations
  • Flexible for flat or curved installation
  • Withstand extreme ambient temperatures

Etched Foil
Our designers use custom software to calculate the configuration of the heating element, given the voltage, wattage and resistance.Our designers use custom software to calculate the configuration of the heating element, given the voltage, wattage and resistance.

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 500°F to -80°F.

 

Advantages over wire wound heating elements:

  • Higher watt densities
  • Distributed wattages
  • Elimination of edge loss compensation
  • Greater element area over heater sheath
  • Higher production quantities
  • Complex heat distribution with a rating of about 200°C (392°F)
  • Economical mass production
  • Reproduction of complex circuits

Wire Wound
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. Precision electronically-controlled winding equipment ensures consistency.The excellent dielectric properties of silicone rubber and the strength of fiberglass combine to produce a unique heater.

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 (392°F).

Silicone rubber heaters resist:

  • Outdoor exposure
  • Many chemicals
  • Vibration
  • Mechanical shock
  • Deterioration by moisture
  • Ripping
  • Stretching
  • Separation
  • Thermal shock
