Silicone rubber heaters are available in wire-wound or etched foil configurations. Wire-wound elements consist of resistance wire wound on a fiberglass thread to provide support and stability. They can withstand repeated bending without affecting their performance and shape. Etched foil can be made from various alloys, including aluminum, stainless steel, non-magnetic nickel-chromium alloys, copper, and constantan, which contribute to their excellent heat transfer capability. Our extensive experience in these materials allows us to design and provide the best solutions for your specific application.
Etched foil heaters utilize chemically etched circuits sandwiched between thin layers of silicone resin, offering rapid heat transfer and precise temperature control. They are recommended for small heaters in high-volume production, outperforming wire-wound elements. Their large flat surface area enables more uniform heat distribution and higher power density, thereby extending the heater's lifespan. For silicone rubber heaters, the leads are then connected to the heater and insulated with additional silicone rubber or epoxy cement to complete the heater.
Silicone rubber flexible heaters can be installed on flat or curved surfaces. Their design slightly varies depending on the chosen installation method. Therefore, specifying the correct installation method to the manufacturer is crucial when specifying the design requirements for silicone rubber heaters. Here are several common installation methods for silicone rubber heaters:
