Sil-Pad A2000 is a conformable elastomer
with very high thermal conductivity that acts
as a thermal interface between electrical
components and heat sinks. Sil-Pad A2000 is
for applications where optimal heat transfer is
a requirement.
This thermally conductive silicone elastomer is
formulated to maximize the thermal and
dielectric performance of the filler/binder
matrix.The result is a grease-free, con-
formable material capable of meeting or
exceeding the thermal and electrical require-
ments of high reliability electronic packaging
applications.

1) The ASTM D5470 test fixture was used.The recorded 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 Include:
• Motor drive controls
• Avionics
• High-voltage power supplies
• Power transistor / heat sink interface
Configurations Available:
• Sheet form, die-cut parts and roll form
• With or without pressure sensitive adhesive
