TgardTM K52
Thermally Conducve 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 52ºC 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 re-
sistance available with thermal properties that are still in the high performance category.
FEATURES AND BENEFITS
• High breakdown voltage of 4,000 – 9,000 range VAC
• Resistant to tears and cut through
• Total thermal resistance of 0.13 - 0.30
range ºC-in2/watt at 20 psi clip force
