It represents one BERGQUIST HIFLOW THF 900 is a phase change material conducting layer in a three- layer laminate. The Hi-Flow coatings are phase change coated on both sides of an aluminum substrate .It is designed compounds. These layers willrespond to heat and pressure induced stresses. The overall conductivity of the material inpost-phase change,thin filmproducts is highly dependent upon specifically to replace grease as a thermal interface, the heat and pressure applied. This characteristic is not accounted for inASTM D5470. eliminatingthe mess, contamination and difficulthandling Please contact Bergquist Product Management ifadditionalspecifications are required. 2) The ASTM D5470 test fixture was used and the test sample was conditioned at 70C prior associated with grease . to test. The recorded value includes interfacialthermal resistance. These values are provided for reference only. Actual application performance is directly related to the surface roughness, BERGQUIST HI FLOW THF 900 is tack-free and scratch flatness and pressure applied. resistant at room temperature and does not require a protective linerinshipment when attached to a heat sink .
