e-Sil 300 Series

Conductive Nickel-Graphite Silicone

 Download as PDF
e-Sil 300 series is composed of a silicone elastomer filled with Nickel plated Graphite particles exhibiting high electrical conductivity, providing highly effective shielding and offering excellent moisture sealing. These excellent performance coupled with enhanced environmental resistance with non or very slight deterioration of conductivity and shielding effectiveness in adverse environment enable wide range of commercial and military applications. Both e-Sil 367 and e-Sil 366 are high performance materials, in high and low hardness.
 
Good tensile and tear strength.  e-sil 300
Very good compression set to maintain sealing force over verylong period of time.
Effective over a wide range of temperatures.
Good sealing under moderate closing force.
Improved mechanical properties enables molding of complicated geometry and delicate parts.
The material provides cost effective production solutions.
Available in sheets in every thickness and custom die-cut parts with or without pressure sensitive adhesive.
Available as custom molded parts.
