GOF2000 THERMAL GASKET
Laird’s Graphite-over-Foam (GOF), GOF2000 thermal gasket, provides thermal transfer performance
in the form of a traditional wrapped compressible foam gasket. GOF2000 combines the thermal
transfer performance of the Tgon™ 9000 synthetic graphite outside wrap and the repeatable
compression and rebound of a foam core. GOF2000 utilizes Laird LSF series silicone foam allowing
for a UL V0 flammability rating.
FEATURES AND BENEFITS
Efficient thermal transfer over large gaps
High Deflection
Repeatable compression and rebound cycles
Lightweight
Low force thermal interface
Abrasion resistant exterior
Ease of manufacturing for high volume
No bleed from silicone oil or other materials
High operating temperature suitability and UL V0 flammability rating
VALUE
Provides compressible thermal interface for sliding connections. Ideal for insertion
applications.
Ensures thermal interface contact in high movement locations that would separate a
traditional thermal putty, gel, or grease
Offers lower force than traditional thermal gap pads for pressure sensitive applications
Ideal thermal performance for large gap sizes
Improved reliability performance of electronics
RoHS and REACH compliant

APPLICATION
Small cosmetic wrinkles in the part exterior are to be expected in the uncompressed state and do not affect thermal performance.
GOF2000 uses a 30um thick PSA as standard. This 30um is not included in the standard thickness listed in the chart above.
THERMAL CONDUCTIVITY & THERMAL RESISTANCE
Graphite over foam is not a homogeneous material and therefore thermal conductivity is not a constant value across the different
configurations and sizes. The values in the chart below are only for comparison’s sake to traditional thermal gap pads. Thermal resistance is
the more indicative value for design evaluation. Below values are based on representative 5.0mm wide by 25mm long samples. Final part Tr
and Tc can be measured and reported in prototype phase to confirm exact value for the configuration.
A dual layer graphite version of GOF2000 is available for a 20% increase in thermal performance.
