1) This is the measured thermal conductivity of the Hi-Flow coating. It represents one conducting layer in a three-layer laminate. The
Hi-Flow coatings are phase change compounds. These layers will respond to heat and pressure induced stresses. The overall conductivi-
ty of the material in post-phase change, thin film products is highly dependent upon the heat and pressure applied. This characteristic
is not accounted for in ASTM D5470. Please contact Bergquist Product Management if additional specifications are required.
2) The ASTM D5470 test fixture was used and the test sample was conditioned at 70°C prior to test. The recorded value includes
interfacial thermal resistance. These values are provided for reference only. Actual application performance is directly related to the
surface roughness, flatness and pressure applied.
Hi-Flow 105 is a phase change material
coated on both sides of an aluminum
substrate. It is designed specifically to
replace grease as a thermal interface,
eliminating the mess, contamination and
difficult handling associated with grease.
Hi-Flow
®
105 is tack-free and scratch
resistant at room temperature and does
not require a protective liner in shipment
when attached to a heat sink.

TYPICAL APPLICATIONS INCLUDE
• Power semiconductors
• Microprocessors mounted on a heat sink
• Power conversion modules
• Spring or clip mount applications where thermal grease is used
CONFIGURATIONS AVAILABLE
• Sheet form, die-cut parts and roll form
• With or without pressure sensitive adhesive
At 65°C (phase change temperature),
Hi-Flow
®
105 changes from a solid and
flows, thereby assuring total wet-out of the
interface. The thixotropic characteristics of
Hi-Flow
®
105 reduce the pump-out from
the interface.
