AceTRONIC Fiberglass Silicone Rubber Heaters

Silicone Rubber Heater Order Form

AceTRONIC fibreglass reinforced silicone rubber heaters are moisture and chemical resistant. Although thin and flexible, they have a rugged construction and can be made to adhere to practically any surface. These heaters can accommodate holes and cut-outs, and can come with a PSA back or a thermostat. Our heaters are suitable for temperatures below 500°F.

Our silicone rubber heaters consist of many layers of silicone rubber sheets that are bonded together through heat and high pressure. A fiberglass grid (which is visible on the surface) reinforces the silicone rubber sheets. It is possible to make the surface of the heaters smooth (i.e. Make the grid invisible) by covering the fiberglass with a thin layer of silicone.

A uniformly spiraled resistance wire web that covers the entire surface of the heater is embedded within the layers of silicone rubber. This web could be designed such that holes and cutouts are incorporated on the heater.

When rubber heaters are made with a pressure sensitive adhesive backing, a thin layer of aluminum is added prior to the adhesive layer, in order to improve heat transfer and maintain its uniformity. This construction makes our heaters an ideal solution to the requirements of may low and medium temperature applications, which do not conform to the standard shapes, sizes and dimensions of band, strip, cartridge, tubular and coil heaters. Our heaters are CSA certified.

Electrical Terminations & Lead Wire Styles

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 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.

Specifications

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.

Max size: 38” x 98” Thickness: 0.060” Max temp: 450°F Max voltage: 480 VAC Wattage: +5/-10% Standard lead wire: 12” Teflon Insulated Dielectric strength: 1000 VAC

Electrical Heater Control option

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, we should be consulted for their availability.
