Lead wire styles SILFLEX silicone rubber heaters come only with lead wire terminations. Two styles are available:

Teflon or silicone lead wires:

These leads are sandwiched between the silicone layers, and a small patch is placed on the point of exit to provide extra protection. This causes the formation of a slight bump at the point where the wires are attached. To eliminate this problem, the attachment between the internal resistance wire and the lead wire could be made at an external tab.

SJO power cables:

When SILFLEX silicone rubber heaters are used independently in an industrial application, they can be made with power cables that exit from a silicone transition box attached to the heater. Proper electrical plugs are available with the power cables.

 

SILFLEX silicone rubber heaters can accommodate pre-set or adjustable thermostats, thermal cutoffs and external “J” type thermocouples. Each has a specific temperature range and maximum amperage capability; the factory should be consulted for their availability.

The adjacent graph shows the surface temperature that a silicone rubber heater will attain when suspended in 70°F still air. Below 5 w/in² watt density applications, the temperature will rise and stabilize at a temperature below the critical 500°F. It is recommenced to bond the heater to the surface or even use a pressure plate when the application requires watt densities above 5 w/in².
