Hi-Flow 330P is a thermally conductive
phase change material featuring a natural
tack on one side and reinforced with a poly-
imide film.The polyimide film provides a high
dielectric strength and cut-through resist-
ance. Hi-Flow 330P offers excellent handling
and consistent liner peel-off characteristics.
The material is designed for use between
a high power electrical device requiring elec-
trical isolation and its heat sink. Bergquist
recommends the use clips or springs for
phase change materials to assure constant
pressure between the component interface
and the heat sink.

1) This is the measured thermal conductivity of the Hi-Flow wax 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 inter-
facial thermal resistance.These values are provided for reference only. Actual application performance is directly related to the surface
roughness, flatness and pressure applied.
Typical Applications
• Spring / clip-mounted devices
• Discrete power semiconductors
and modules
