Proposition:
Parker Chomerics THERM-A-GAP™
PAD 30 is a thermally conductive
gap ller pad with 3.2 W/m-K thermal
conductivity.
THERM-A-GAP PAD 30 oers the
compelling combination of both
excellent thermal performance and
conformablility, along with the lowest
outgassing to provide an eective
thermal interface between heat sinks
and electronic devices where there
are uneven surfaces, air gaps and
rough surface textures.
THERM-A-GAP PAD 30 has been
specically formulated to conform to
surface irregularities and adhere to a
wide range of component shapes and
sizes.
Product Features:
• 3.2 W/m-K thermal conductivity
• Ultra low deection force
• High thermal conductivity
• High tack surface reduces
contact resistance
• “A” version oers high strength
acrylic PSA for permanent
attachment
• UL recognized V-0 ammability
RoHS compliant
