Thermally Conductive / Non-Flammable Silicone Rubber

“SARCON®”

Our unique product, SARCON® is an advanced silicone rubber with high thermal
conductivity and superior flame retardancy

Function
 
 

As shown below, even the most highly polished mating surfaces do not make reliable contact surfaces. Complete physical contact is necessary to minimize the resistance to heat flow for the best thermally conductive path. Such surface voids, when properly filled with a conformable, SARCON, will in most cases exhibit the continuous characteristics of a solid metal of the same dimensions.


Thermal impedance of semiconductor mounted to substrate is appreciably increased at junction of porous surfaces.

Thermal impedance of semiconductor mounted to substrate with gap filler pad is eliminated yielding higher temperature gradient.
Flame Retardency
 
 

UL File Number: E58126

Applications
 
 
  • Thermal conductive insulators for semiconductors
  • Compression jointing materials for thermistors and temperature sensors
  • Thermal conductive material for all types of heaters
Formulations/Configurations
 
 
  • A variety of specific compounds are available for a wide range of performance requirements in Sheets, Rolls, Die-cuts, Sleeves, Gel, Extrusions, Moldings

SARCON’s versatility in thermal management applications is doubly enhanced by way of the variety of end-use configurations possible, and the many standard material formulations available in each.
The silicone rubber based materials offer other useful elements such as electrical insulation, protective coverings and gasketing as integral features in most designs.
Along with a few simple recommendations to help in obtaining the optimum performance for your application, a few suggestions are included which may help you to take advantage of some of these other features.
More power and light weight. In the past, these two characteristics in electronics were mutually exclusive. Now, micro-electronics are just that, and in addition, need thermal management components to further complement these objectives.
SARCON is an advanced silicone rubber with high thermal conductivity and superior flame-retardancy. By combining the inherent silicone rubber properties of heat resistance, electrical insulation and long-term aging into one compound, this universally applicable material can be made in an unlimited
number of thermal management configurations.

Thermal Transfer
 
 

a.) Consider the most efficient SARCON materials regarding thermal conductivity.
b.) Take advantage of the heat transfer characteristics of any nearby sheet metal, heat sink and case components by using the SARCON component as a thermally conductive bridge from the heat generating component to the components. See drawing at left.
c.) Note also that SARCON is very elastic, providing a very tight fit over uneven surfaces. This eliminates the need for gap-filling agents in order to achieve high rates of thermal dissipation without variation. The sleeves and cases can be designed as an interface fit which can slip snugly over appropriately configured components.
Attachment
 
 

a.) No special preparations are necessary to attach the SARCON component.
b.) Some of the most common alternatives include: pressure sensitive adhesive silicone adhesive mechanical clamping hardware attachment – screws, rivets self-adhering silicone gel
c.) Consider using SARCON Gap Filler Pads shown on this catalog product section.
