of Silicone Rubber & Kapton SILICONE RUBBER HEATERS Durex’s silicone rubber heaters take advantage of the unique properties of silicone rubber to provide heating elements of unparalleled performance. Silicone rubber is calendared onto fiberglass cloth in a variety of thicknesses and constructions which serves as the basis for Durex’s silicone heating elements. Generally two layers of material containing an etched foil element or a precision wire wound element are vulcanized together to form a basic silicone heating element. The three most common constructions include: • .030” nominal...

of Silicone Rubber & Kapton SILICONE RUBBER HEATERS Engineering Specifications Wattage Durex can provide silicone rubber heaters with a variety of wattage and power options. Although uniform watt density (watts per square inch) is the most common configuration, Durex engineering can profile the power density to supply the heat where it is needed in the application. A common scenario is when heating a plate, the outer perimeter can be manufactured with a higher watt density to minimize edge loss and yield a more uniform temperature across the surface. Silicone rubber heaters can also be...

of Silicone Rubber & Kapton SILICONE RUBBER HEATERS Attachment Methods Durex silicone rubber heaters can be attached to customer parts by a variety of methods. Many factors can influence the optimal choice including heater watt density, operation temperature, geometry of part, and part material. Contact Durex engineering to discuss the best method for a specific application. Factory Vulcanization Flex Heaters Simultaneously with the vulcanization of the two silicone layers for the heating element, Durex can vulcanize (attach) the heating element to the customer’s part. Factory vulcanization...

of Silicone Rubber & Kapton SILICONE RUBBER HEATERS Temperature Control Thermostats Durex silicone rubber heaters can be designed and manufactured with a variety of thermostats. Generally these thermostats provide over temperature (safety) control or temperature control in applications not requiring a tight, precise, temperature control. Durex engineers can achieve a variety of results depending on the thermostat placement. For over temperature protection the thermostat is generally placed over a heated section so that the heating element does not exceed a maximum temperature. By placing...
