Bergquist hi flow 300p thermally conductive phase change interface material bergquist hf300p 0 0015 00 0404 hi flow 300p consists of a high performance phase change compound coated on a thermally conductive and electrically isolating carrier that is designed as a replacement for grease as a thermal interface at a lower phase change temperature of 55 deg c the material changes from a solid and flows thereby assuring total wet out of the interface the thixotropic characteristics of the ma
