Silicone Rubber Heaters
Epec silicone rubber flexible heaters can be custom designed to various shapes and sizes, ranging from 1” X 1” to 18” X 24”. If larger sizes are needed, then switching from an etched element to a wire element would be required. Based on the element used, the overall average thicknesses are 0.030" (etched element) to 0.056" (wire wound).
The etched or wire circuit is attached to power leads with solder and then vulcanized between two layers of silicone rubber, resulting in a completely homogenous unit. The silicone offers protection from physical damage such as scraping or scuffing and acts as a moisture barrier to allow for operation in wet and outdoor environments. Silicone is also resistant to most chemicals.
We offer multiple heating elements for silicone heaters such as stainless steel 304, CuNi44, and Inconel600, with excellent dielectric properties and operating environments between -70°F (-56.6°C) and 392°F (200°C). It should be noted that silicone heaters have a delay of transfer from the resistive foil or wire to the mounting surface.
