Parker Chomerics THERM-A-GAP
GEL 37 is a high performance, one
component, dispensable thermal
interface material with 3.7 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 37 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.
Product Features
• Thermal conductivity: 3.7 W/m-K
• Easily dispensed
• No secondary curing required
• Low thermal impedance
• Very low compression force
• Reworkable
