Silicone and Custom Rubber Heaters
Silicone Rubber is the most versatile rubber-based dielectric used to produce flexible surface heaters. Both etched foil and wire wound element designs are offered; the application determines the choice. Fiberglass reinforced Silicone Rubber Heaters are thin and flexible, durable, and have a long shelf life.
Etched foil element is encapsulated within two layers of fiberglass-reinforced silicone; these heaters have the ability to provide heat exactly where it is required and are rugged, moisture and chemically resistant. They are easily bonded to metalwork through a process called vulcanization.
Other rubbers such as EPDM, a synthetic rubber, and custom compounds including pigmentation/colors can be made.
Etched foil designs afford more heater sizes, shape opportunities and enhance the longevity potential. Watt density distribution and thermally conductive and insulative materials. Pressure sensitive adhesive (PSA) and factory bonding methods are available.
Silicone Rubber heaters from Thermal Circuits offer many benefits including custom watt densities, thin profiles, ease of placement and low thermal mass. They are easy to apply and provide high heat output.
Silicone and Custom Rubber Heaters – Applications
220ºC Custom Geometry Commercial and Industrial Heaters
Conductive Heater Assembly with Silicone Rubber Insulation.
200ºC Hot Plate Assembly for Re-Thermalization of Food
Hospitals and institutions serve meals from multi-tiered thermalization food serving carts or corridor/floor transport serving consoles. Meals are cooked, frozen and stored in the carts to be heated and served at a later time. Thermal Circuits manufactures assembly modules including silicone rubber insulated etched foil heaters vulcanized to anodized aluminum platens outfitted with thermostats and overtemperature devices. The modules can be rectangular or round to fit the specifications of the cart and are manufactured to withstand the rigors of steam cleaning.
220º High Temperature, Conductive Heater Assembly with Kapton® Polyimide Insulation
Heater for Electronic Enclosure Valve Heaters
Conductive heater assembly with Kapton® Polyimide dielectric insulation. Bonded to machined metalwork with thermistor, wire harness and connector.
Mobile Intravenous Bag Heater
Used by paramedics and EMTs to provide warmed lifesaving fluids.
Conductive Heater Assembly with Silicone Rubber Insulation, vulcanized to the inside diameter of metal cylindrical IV bag warmer with thermal fuse and lead wire.
220ºC Silicone Rubber Heater for Thermal Cycler used in Medical R&D
High Temperature Heater Assembly
The silicone insulation both bonds and vulcanizes the heater to a machined metal plate and provides dielectric insulation. Temperature control of this dual zone assembly is achieved by potted thermistors and sensor and thermal cutoffs (TCO).
220ºC Display Backlight Reflective Heater
The silicone rubber heater is Room Temperature Vulcanized (RTV) to a display backlight reflector.
