GP300
Gap Pad
GP300 is a silicone, thermally conductive material for use at a thermal interface. GP300 is specifically
developed as a low thermal resistance gap pad.
 Works well under low pressure
 Good thermal conductivity; 3.0 W/m.K
 Excellent electrical insulation
 High heat dissipation; low thermal resistance
Approvals RoHS-2 Compliant (2015/863/EU): Yes
