Features and Benefits

• Thermal impedance:

• Electrically isolating

• 65°C phase change compound coated

• Tack-free and scratch-resistant

Hi-Flow 625 is a film-reinforced phase change

material.The product consists of a thermally

conductive 65°C phase change compound

coated on PEN film. Hi-Flow 625 is designed

to be used as a thermal interface material

between electronic power devices that

require electrical isolation and a heat sink.The

reinforcement makes Hi-Flow 625 easy to

handle, and the 65°C phase change

temperature of the coating material eliminates

shipping and handling problems.The PEN film

has a continuous use temperature of 150°C.

Hi-Flow 625 is tack-free and scratch-resistant at

production temperature and does not require

a protective liner in most shipping situations.

The material has the thermal performance of

2-3 mil mica and grease assemblies.

THERMAL PERFORMANCE vs PRESSURE

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 conductivity

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.
