Tgard K52

High Thermal and Dielectric Performance Insulator Pad

Tgard K52 is a high thermal and dielectric performance insulator pad consisting of a ceramic filled phase change compound coated on MT Kapton film.

Tgard 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.

• 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
