Parker Chomerics THERM-A-GAP™
PAD 80 is a high performance,
thermally conductive gap filler pad
with a typical 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.
PAD 80 is available in standard
thicknesses as low as 0.030” to
0.200” (0.76mm 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.
• 8.3 W/m-K thermal conductivity
• Very low compression force
• Electrically isolating
• UL 94 V-0 flammability rating
• “A” version offers high strength
acrylic PSA for permanent
attachment
• Passes NASA outgassing
requirements
• 5G and Telecom equipment
• Smart home devices
• Automotive electronics
• LEDs
• Power supplies
• Computing modules and servers
• Memory and data storage units

THERM-A-GAP™ 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 5% 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.
