Silicone Rubber Heaters

Silicon and Flexible Rubber Heater

Silicone Rubber Heaters manufacturer, DT Heaters and Controls offers a high watt density while maintaining flexibility. Due to the malleable characteristic of the silicone rubber heaters, they are an excellent choice for uneven surfaces.  The variety of shapes that you can create using a silicon rubber heater allows heat to be delivered where it is most needed. These Silicone Heaters improve heat transfer; speed warm ups, and reduces wattage requirements. Because very little material separates the silicon rubber heater element from the part, heat transfer is fast and efficient. Fiberglass-reinforces the silicone rubber heater and gives it dimensional strength without sacrificing flexibility. The silicone rubber heater construction creates a very thin heater allowing it to fit applications where space is limited. Silicone Rubber Heaters provide steady performance and are able to provide more wattage than Polyimide Electric Heaters.  Silicone rubber heaters can also be custom molded into shapes with insulation on top of the silicone rubber heater.  Another variety of the silicone rubber heater is the stretch to length silicone rubber heater.  Your number one source for silicone rubber custom designs.
