INSULATION CHARACTERISTICS

HEATFLEX silicone rubber heaters are manufactured by placing a wire wound or etched circuit element between two or more layers of fiberglass reinforced silicone rubber. These layers can be a variety of thicknesses depending upon the design requirements. Basic design thickness selections are as follows:

• .020" – For etched circuit elements where extremely efficient heat transfer is necessary. This is thinnest construction available.
• .030" – Standard thickness for silicone rubber heaters containing etched circuit elements. This thickness may also be used for economically priced silicone rubber wire wound heaters.
• .040" - Standard thickness for silicone rubber wire wound heaters when they will be permanently attached. This is a construction with .015" between the element and the part to be heated and .025" on the topside to provide insulation and added protection.
• .055" – Thickness standard silicone rubber wire wound heater constructed. This construction is most suitable for heaters that are not permanently attached. .028" silicone rubber is used on either side of the element. This is a common construction for drum heaters and flexing applications.
