Silicone Rubber Fiberglass Flexible Heater

Silicone rubber fiberglass insulated flexible heaters SRFRA and SRFGA series can improve heat transfer and speed warm-ups where controlled heating is required in confined areas. Two circuit designs are available: etched foil or wire wound. Heaters with etched foil designed elements are available where the length or width dimension is less than 254 mm. All other heaters where both the length and the width dimensions exceed 254 mm use the wire-wound element design.

Effect of power density: gentle warming is best done with 2.5 W/in2. An excellent all-purpose unit is the 5 W/in2. Rapid warm-up and high temperature are achieved with the 10 W/in2; however, the temperature must be controlled as the safe maximum operating temperature limit of 232°C may be exceeded.
