Silicone Rubber Heater

SVE Silicone Rubber Heater are constructed by vulcanizing a wire wound nickel- chrome wire or etched nickel-chrome foil between two layers of silicone rubber. Flexible heaters are regularly specified because of their light weight, thin profile, low thermal mass and flexibility. The abilities to provide an infinite array of patterns and concentrations of heat are additional characteristics. Complex shapes, contours and three-dimensional patterns are possible. Many mounting methods are available for the application of Flexible Heaters. They are available with thermostats, thermocouples, mounting holes and pressure sensitive adhesive (peel and stick). These are available in thickness ranging from 0.2mm to 6mm
Wire Wound Element: A fine gauge resistance wire is spiralled around a fiberglass core. The element is placed in a specifically designed pattern and vulcanized to a silicone rubber substrate. Advantages versus etched foil elements are: Physical strength; flexibility; smaller production quantity; conforms well to small radius bends and larger possible sizes.
Etched Foil Element: The manufacturing process of etched foil elements is adapted from the production of printed circuit boards. A nickel resistance alloy foil is acid etched to the specific pattern, then vulcanized to the sheath material. Advantages versus wire wound are: Higher watt densities; greater area coverage of element over heater sheath; higher production quantities and complex heat distribution.
