It represents one conducting layer in a three- layer laminate. The Hi-Flow coatings are phase change change material . The product consists of a thermally compounds. These layers willrespond to heat and pressure induced stresses. The overall conductive 65C phase changecompound coated on PEN film. conductivity of the material inpost-phase change,thin filmproducts is highlydependent upon the heat and pressure applied. This characteristic is not accounted for inASTM D5470. BERGQUIST HIFLOW THF 500 is designed to be used as a Please contact Bergquist Product Management ifadditionalspecifications are required. thermal interface material between electronic power devices 2) The ASTM D5470 test fixture was used and the test sample was conditioned at 70C prior that require electricalisolation and a heat sink . 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, flatness and pressure applied. The reinforcement makes BERGQUIST HI FLOW THF 500 easy to handle,and the 65C phase changetemperature of the coating material eliminates shipping and handlingproblems . GENERAL INFORMATION The PEN filmhas a continuous use temperature of 150C . For safe handling information on this product, consult the Safety Data Sheet, (SDS). BERGQUIST HI FLOW THF 500 is tack-free and scratch resistant at production temperature and does not require a Not for product specifications protective linerinmost shipping situations .
