Hi-Flow 565U

Hi-Flow 565U is a thermally conductive phase change material which is applied in tabulated pad form. In the application the easy to use material undergoes a phase change at 52°C. After phase change, Hi-Flow 565U wets out the thermal interfaces resulting in a very low thermal impedance.

Hi-Flow 565U displaces easily at low pressures to provide a thermal performance comparable to the best thermal greases. Hi-Flow 565U is provided at a consistent thickness to ensure reliable performance. Hi-Flow 565U is attached to the target surface via pressure from a hard rubber roller or squeegee.
