Features and Benefits
• Thermal impedance:
• Can be applied directly to a cold heat sink
• One side adhesive-coated to aid
• Fiberglass reinforced
Bergquist Hi-Flow 115-AC is a thermally
conductive fiber reinforced phase change
material.The product consists of a thermally
conductive 65°C phase change compound
coated on a fiberglass web, and an adhesive
coating on one side for attachment to a cold
heat sink.There is no need to preheat the
heat sink to apply the Hi-Flow 115-AC.
Hi-Flow 115-AC is designed as a thermal
interface material between a computer
processor and a heat sink.The pressure
sensitive adhesive makes it simple to apply in
high volume to heat sinks and the 65°C phase
change temperature eliminates shipping and
handling problems.
Hi-Flow 115-AC requires no protective liner
for shipping or handling.The Hi-Flow coating
has excellent handling characteristics at room
temperature, and can withstand the handling
and shipping process without protection.
Hi-Flow 115-AC handles like a Sil Pad at
room temperature and flows like high-quality
grease at elevated temperatures.

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 (Bergquist modified) 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.
