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”
(2.5mm).
** 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.
