The etched or wire circuit is soldered to the power leads, then vulcanized between two layers of silicone rubber to create a homogeneous device. The silicone provides physical protection against scraping and scuffing and acts as a moisture barrier to allow operation in damp and outdoor situations. Silicone is chemically resistant as well.

Salient Features

  • Silicone Heating Pads can be manufactured for various amperes or wattages with a maximum watt density of 60 W/in².
  • Silicone heaters are heat-transfer efficient and have tight tolerances, and they can work in temperatures as low as -76 °F (-60 °C) and as high as 446°F (230 °C).
  • Thermostats to measure temperature can be attached to silicone heating pads, temporarily or permanently.
  • Silicone heating pads can be strapped, clamped, magnetized momentarily, or permanently vulcanized to cylindrical components in the factory.
  • These have a wattage tolerance of ±10%.
  • The dielectric strength of a Silicone Heating Pad is 1000 VAC.
  • They are constructed with wire-wound or etched-foil elements.

Manufacturing Process of a Silicone Heater

The manufacturing process of a silicone heater consists of the following steps:

  • First, the texture of the silicone material is chosen; this can either be smooth or rough, depending on flexibility and texture.
  • Based on silicone rubber heater technology, the lengths of the flexible heater are coiled like a telephone cord.
  • The lead wires are supported structurally by the molded end protector, which clamps around a pipe.
  • To prevent condensation and contamination in the wafer process, it is crucial to have a consistent gas temperature in the supply lines.
  • A cylinder-shaped piece that "snaps" into a pipe of the same diameter is a common design.
  • Multiple layers can be applied for a thicker heater application.
Manufacturing Process of a Silicone Heater

Material Used in a Silicone Heater

The materials used in a fiberglass/silicone heater depend upon the type of element used. The wire-wound element contains different types of resistance wire:

  • Nickel Chrome

    These alloys are non-magnetic with high resistivity and good oxidation resistance. These have a maximum temperature of up to 2280 °F (1248.9 °C).

  • Iron Chrome Aluminum

    These alloys are high-resistance materials with very good form stability. They provide longer element life, have higher surface loading capabilities, and lower density.

  • Copper-Nickel

    These alloys have a low-temperature coefficient of resistance and a medium range of electrical resistivity.


The etched-foil elements contain the following materials:

  • Chemically etched circuits laminated between thin sheets of silicone
  • Traditional print/etch technology
  • Alloys such as stainless steel, aluminum, non-magnetic alloys, constantan, copper, nickel-chrome, or others
Etched Foil Silicone Rubber Heater

Circuit Design for Rapid Heating

  • Resistance wire is glued to the silicone rubber in wire-wound silicone rubber heaters to guarantee physical robustness and uniform heat distribution.
  • Chemically etched circuits are sandwiched between thin silicone sheets to guarantee rapid heat transmission in the etched foil silicone flexible heaters.
  • When combined with temperature control devices, silicone rubber flexible heater create high output voltage, assure even heat distribution, and provide improved temperature control.
  • Silicone heaters have a watt density of 30 watts per square inch and may be built as thin as 0.020 inches (0.5mm). They can resist 750 volts. As a result, silicone heaters are capable of quick thermal recovery and even heat distribution.
  • The temperature range of these heaters is -40 °F (-40 °C) to 392 °F (200 °C), so they are suited for cryogenic and high-temperature applications.

Applications of Silicone Heaters

Silicone rubber heating elements are used in various applications owing to their benefits to industrial, commercial, and military applications. Here are some Industrial application areas:

  • Protect liquids and viscous materials from cold temperature: Silicone rubber can adhere to the walls of metal condensation tanks to keep liquids and viscous materials above the freezing point.

  • Prevent condensation: Silicone rubber heaters may be used to prevent condensation in any enclosed environment.

  • Prevent corrosion: Silicone rubber heaters can be attached to the inside walls of tanks or hoppers to keep the surface temperature above the point at which moisture forms.

Other areas include:

  • Electronics
  • Telecommunications equipment
  • 3D printing
  • Aerospace manufacturing
  • Food processing and storage
