Heater Catalog - Watlow

Flexible HeatersSilicone Rubber HeatersRugged, yet thin, lightweight and flexible—use ofWatlow ® silicone rubber heaters is limited only by theimagination. Heat can be put exactly where it is neededto improve heat transfer, speed warm ups and decreasewattage requirements in an application process.Fiberglass-reinforced silicone rubber provides dimensionalstability without sacrificing flexibility. Because very littlematerial separates the element from the part, heat transferis rapid and efficient. Heaters are constructed with awire-wound element or with an etched foil element. Itsthin construction allows it to fit into applications wherespace is limited.Performance Capabilities• Operating temperatures up to 500°F (260°C)• Watt densities up to 80 W/in 2 (12.5 W/cm 2 ), dependentupon application temperature• Wire-wound element thickness — 0.055 in. (1.4 mm)• Etched foil element — 0.022 in. (0.56 mm)• UR ® , cUR ® , VDE and CE recognitions are available onmany designs up to 428°F (220°C)Features and BenefitsDesigned to the exact shape and size needed• Conforms to component and/or equipmentMore than 80 designs available immediatelyfrom stock• Reduces downtimeConstructed with wire-wound or etched foilelements• Enables a thin, lightweight heater• Provides the desired flexibility for many dynamicapplications• Delivers low mass and easily repeatable distributedwatt densitiesMoisture and chemical-resistant silicone rubbermaterial• Provides longer heater lifeVulcanizing adhesives or fasteners• Allows heaters to be easily bonded to partsTypical Applications• Semiconductor processing equipment• Freeze protection and condensation prevention formany types of instrumentation and equipment• Medical equipment such as blood analyzers and testtube heaters• Computer peripherals such as laser printers• Curing of plastic laminates• Photo processing equipment0.055 in.
