Parker Chomerics THERM-A-GAP™ GEL
50VT is a reworkable, high performance,
one-component silicone, dispensable
thermal interface gel material with 5.2
W/m-K typical thermal conductivity. GEL
50VT was developed to conduct heat
away from electronics to heat sinks or
enclosures and to perform reliably in
vertical and/or high vibration applications.
The “VT” suffix in the product name stands
for “Vertical Tackiness.”
During development, GEL 50VT was tested
to a number of rigorous long term reliability
tests such as automotive slump, high
vibration testing, and telecommunications
thermal verification processes. The long-
term reliability of GEL 50VT provides
confidence for mission critical applications
that rely on consistent thermal performance
over many years of continuous operation.
THERM-A-GAP™ GEL 50VT requires
no mixing or secondary curing and is
designed for easy application and rework.
It can be dispensed at various bond line
thicknesses typically up to 0.160in (4mm)
to take up gaps created by assembly or
manufacturing tolerances. As with all
Parker Chomerics thermal gels, GEL 50VT
is formulated to accommodate today’s
high-performance and high- reliability
electronics while being ideal for automated
dispensing machines, rework, and field
repair situations.
