Flexible Heaters

Silicone Rubber Heaters


Watlow silicone rubber heaters are rugged, yet thin, lightweight and flexible. Use of these heaters is limited only by the imagination. Heat can be put where it is needed. These silicone heaters improve heat transfer, speed warm ups, and decrease wattage requirements.

Fiberglass-reinforced silicone rubber gives the heater dimensional stability without sacrificing flexibility. Because very little material separates the element from the part, heat transfer is rapid and efficient. The silicone rubber heaters are constructed with a wire-wound element or an etched foil element. The heater construction creates a very thin heater allowing it to fit applications where space is limited.

Polyimide Heaters


Polyimide is a thin, lightweight organic polymer film which provides excellent tensile strength, tear resistance and dimensional stability. This heater is ideal for applications requiring low outgassing in a vacuum, or resistance to
radiation, fungus and chemicals. Polyimide is also solvent resistant

Stretch To Length Heating


The STRETCH-TO-LENGTH® heater is the perfect solution for semiconductor gas line applications requiring precise temperatures to prevent condensation or over-temperature breakdown of critical process chemistries. As a superior alternative to heat tape, Its preformed construction allows it to be wrapped around the delivery line enabling consistent heater/gas line contact and improved temperature uniformity.

The STRETCH-TO-LENGTH gas line heater is the perfect solution for semiconductor processes where condensation of critical gases occurs due to a phase shift at low temperatures. High or low temperature conditions could result in undesirable particulates and result in costly device defects and tool maintenance.

The STRETCH-TO-LENGTH heater’s preformed wrapping capability provides engineers with the flexibility needed to compensate for different sized components, thereby reducing the potential for hot and cold spots.
The system includes a 2 W/in2 STRETCH-TO-LENGTH heater and silicone rubber foam insulation.
