Flexible silicone rubber heaters are versatile and can be used in a wide variety of applications. Silicone rubber, which is used to produce flexible silicone heater pads, has a low thermal mass, excellent electrical insulation and rugged construction. This allows these rubber heating mats to have very high power densities (more watts/sq inch) and react quickly to thermostats or temperature controllers to keep process temperatures accurate. Since the properties used to make silicone rubber are non-reactive and stable, the heaters are also able to operate in a wide range of temperatures ( –76°F to 446°F). When you combine all of these attributes with the fact that silicone heating pads are thin (2-3mm nominally) and comparatively lightweight, it gives the product a clear advantages over other heating options.
The Heating Process
When you need heat to be a precise temperature, silicone heating pads provide the best solution. Applying heat directly to the item can be accomplished by either strapping the flexible heating pad on via hooks-n-springs or separate straps or utilizing our All Weather, High Temperature PSA (Pressure Sensitive Adhesive). CHR utilizes a propriety PSA which was created by Nitto Denko Corp. and allows our silicone heater pads to be installed in areas with complex shapes and have excellent direct contact. This makes the heating process very efficient. This is especially useful when working with a high watt density heater and ensuring intimate contact with the object to be heated.
Types of Silicone Heater Pads
Custom Heaters & Research (CHR Inc.) offers two main styles for constructing rubber heating mats: Wire Wound and Etched Foil.
