Silicone Rubber Heater Pads

Rugged, yet thin, lightweight and flexible, Watlow silicone rubber heaters place heat exactly where it's needed to improve heat transfer, speed warm ups and decrease wattage requirements in an application process. Fiberglass-reinforced silicone rubber gives the heater dimensional stability without sacrificing flexibility, and because very little material separates the element from the part, heat transfer is rapid and efficient. The heaters are constructed with a wire-wound or an etched-foil element, and their thin construction allows them to fit into applications where space is limited.

Key Features

• Designed to the exact shape and size needed — Conforms to your component and/or equipment.
• More than 80 designs available immediately from stock — Reduces downtime.
• Constructed with wire-wound or etched-foil elements — Delivers a thin, lightweight heater, provides the desired flexibility for many dynamic applications, and delivers low mass and easily repeatable distributed watt densities.
• Moisture- and chemical-resistant silicone rubber material — Provides longer heater life.
• Vulcanizing adhesives or fasteners — Allows heaters to be easily bonded to the part.

Performance Capabilities

Operating temperatures up to 500°F (260°C), watt densities up to 80 W/in² (12.5 W/cm²) dependent upon application temperature, wire-wound element thickness of 0.055 in. (1.4 mm), etched-foil element thickness of 0.022 in. (0.56 mm), and UR®, cUR®, VDE and CE recognitions available on many designs up to 428°F (220°C).

Typical Applications

Silicone rubber heaters are used for freeze protection and condensation prevention across many types of instrumentation and equipment, medical equipment such as blood analyzers and test tube heaters, computer peripherals such as laser printers, curing of plastic laminates, photo processing equipment, and semiconductor processing equipment.

Mounting Methods

Heaters can be mounted with pressure sensitive adhesive, a silicone contact cement kit, field applied adhesives (silicone RTV), mechanical fasteners, or factory bonding.
