Sil-Pad K-4
The Original Kapton
-Based Insulator
Features and Benefits
Thermal impedance:
0.48°C-in2/W (@50 psi)
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.
Typical Applications Include:
Power supplies
Motor controls
Power semiconductors
Configurations Available:
Sheet form, die-cut parts and roll form
With or without pressure sensitive adhesive
