TgardTM K52 Thermally Conductive Insulators HIGH THERMAL AND DIELECTRIC PERFORMANCE INSULATOR PAD TgardTM K52 is a high thermal and dielectric performance insulator pad consisting of a ceramic filled phase change compound coated on MT Kapton film. TgardTM K52 phase change coating all but eliminates contact thermal resistance. The phase change coating melts at 52C and replaces all contact areas that contain air. TgardTM K52-1 is ideal for applications requiring the best thermal performing insulator material. TgardTM K52-2 has the best balance of thermal, dielectric and cut through performance. TgardTM K52-3 is a 3 mil MT Kapton film that provides the best crush and cut and tear resistance available with thermal properties that are still in the high performance category.
