Gap Pad 2000SF
®
Thermally Conductive, Silicone-Free Gap Filling Material
Features and Benefits
• High thermal conductivity: 2 W/m-K
• Natural inherent tack reduces interfacial
thermal resistance and aids assembly
• Conforms to demanding contours
and maintains structural integrity with
little stress applied to fragile component
leads
• Fiberglass reinforced for puncture, shear
and tear resistance

Gap Pad 2000SF is a silicone-free insulating
material. Silicone-sensitive applications benefit
from this fiberglass-reinforced gap filling
material, which combines electrical isolation
with exceptional thermal performance
(2.0 W/mK).While highly thermally conduc-
tive, the material is exceptionally soft and
more compliant than other silicone-free
materials. Gap Pad 2000SF is capable of
conforming to the most demanding contours
while applying little stress on component
leads.

. For more information on Gap Pad modulus, refer to Bergquist Application Note #116. 3) The ASTM D5470 test fix-
ture was used.The recoded value includes interfacial thermal resistance.These values are provided for reference only. Actual application
performance is directly related to the surface roughness, flatness and pressure applied.
Typical Applications
