Customer Value
Proposition:
Parker Chomerics THERM-A-GAP GEL 75
is a high performance, one component,
dispensable thermal interface material
with 7.5 W/m-K thermal conductivity
developed to conduct heat from
electronics to a heat sink or enclosure.
The material’s heavy paste-like
consistency enables controlled
dispensing, applied in variable
thicknesses to suit application needs.
THERM-A-GAP GEL 75 requires
low compressive force to deform
under assembly pressure subjecting
components, solder joints and leads to
minimal stresses.
It is formulated to accommodate today’s
high performance electronics and is ideal
for automated dispensing machines,
rework and field repair situations.
