Proposition
Parker Chomerics THERM-A-GAP™ PAD
80 is a high performance, thermally
conductive gap filler pad with a thermal
conductivity of 8.3 W/m-K. It provides
superior heat transfer across a range
of thicknesses while maintaining low
compression forces and conformability
between mating surfaces.
THERM-A-GAP™ PAD 80 is designed to
serve as an effective thermal interface
between heat sinks and heat generating
components on electronic devices where
uneven surfaces, air gaps, and rough
surfaces may exist. This material exhibits
low silicone oil bleeding and is ideal for
high thermal performance needs across
industries.
PAD 80 is available in standard
thicknesses from 0.020” to 0.200” (0.50mm
to 5.1mm) and can be provided in sheets
or cut to custom part sizes. It is available
on several material carriers including
an aluminum foil carrier that is supplied
with pressure sensitive adhesive (PSA)
for added adhesive strength during the
assembly process.
Product Features
• 8.3 W/m-K thermal conductivity
• Very low compression force
• Electrically isolating
• Low silicone oil bleeding
• UL 94 V-0 flammability rating
• “A” version offers high strength
acrylic PSA for permanent
attachment
• Passes NASA outgassing
requirements

PAD 80 Product Information
† Typical properties: these are not to be construed as specifications.
* Thickness tolerance, inches(mm) is ±10% of the nominal part thickness for parts 0.100” (2.5mm) thick or less; those parts greater than 0.100” (2.5mm) thick are held to ±0.010”
(0.25mm).
** The typical deflection range of Therm-A-Gap 80 is approximately 15% to 40% (or more depending on the carrier option and pad thickness. Evaluation of the part in your specific
application is recommended.) Samples are available upon request.
