SILICONE RUBBER HEATERS MARATHON HEATER

Wire wound Silicone Rubber Heaters Marathon Heater flexible heaters provide outstanding performance in applications up to 450°F under a variety of operating conditions. Properly applied silicone rubber heater life routinely exceeds 10 years. Silicone rubber has a high dielectric strength and is flame retardant and non-toxic. Design versatility permits special heat profiles allowing zones of higher or lower heat concentration as needed. Their flexible construction makes them very easy to install on a variety of surfaces. Silicone Rubber Heaters can be mounted to flat or curved surfaces. They...

Standard Specifications Maximum recommended watt density for standard wire wound Silicone Rubber Heaters is 5 watts/sq. in. Please note that higher watt densities are only recommended for very specific conditions. Please consult the chart below to determine the maximum watt density for your application. Using lower than recommended watt densities will result in increased heater life.
