Features and Benefits

• Thermal impedance:

• Withstands high voltages

• High dielectric strength

• Very durable

Sil-Pad K-4 uses a specially developed film

which has high thermal conductivity, high

dielectric strength and is very durable. Sil-Pad

K-4 combines the thermal transfer properties

of well-known Sil-Pad rubber with the physical

properties of a film.

Sil-Pad K-4 is a durable insulator that with-

stands high voltages and requires no thermal

grease to transfer heat. Sil-Pad K-4 is available

in customized shapes and sizes.
