Surface heater (Rectangular & Square)

Designed for Trouble-Free Performance and Improved Operation Efficiency

These flexible heaters are capable of operating with excellent performance under many adverse conditions, including: moisture, outdoor exposure or ambient temperatures, radiation, ozone, compression set, vacuum, fungus, oils, solvents, and many other chemicals.

Flexible Silicone Rubber and Kapton Heaters also have very good mechanical properties. They are of low mass construction and provide rapid heat-up due to direct bonding to the part. Flexible Heaters are not affected by mechanical shock, vibration or repeated flexing and will not stretch or tear over a temperature range of -392°F to +500°F (-236°C to +260°C).

Flexible heaters provide excellent heat transfer with rapid heat-up and cool-down response to the temperature control — a desired requirement for applications where precise temperature control is important to the overall quality of the application. Tempco flexible heaters are made in two insulating materials. Silicone Rubber, up to 500°F (260°C), and Kapton®, a lightweight organic polymer film offering dimensional stability, excellent tear resistance and tensile strength, used only for etched foil elements up to 392°F (200°C).

Silicone Rubber Heater Surface Temperature vs. Watt Density

This graph shows the relationship between the maximum surface temperature and the watt density of standard silicone rubber heaters. The heater was energized in still air without insulation or a load. Using this graph the designer can estimate the maximum temperature the heater can reach compared to the watt density of the heater.
