Thermal impedance: 1.07°C-in2/W (@50 psi)
Excellent cut-through resistance
Use in screw mounted applications with cut-through problems

In addition to excellent heat transfer and dielectric properties, Sil-Pad 980 is specially formulated for high resistance to crushing and cut-through typically found in high-pressure applications where surface imperfections such as burrs and dents are inherently common. (e.g. heavily-machined metal surfaces manufactured from extrusions or castings).

With a field-proven history of reliability, Sil-Pad 980 is Bergquist's best material for cut-through resistance in screw-mounted and other applications with cut-through problems.

The cut through resistance of Sil-Pad 980, K4, SP400KS have been measured using a combination cut-through/voltage breakdown test. A 1”x1” test sample was placed on 2”x2” base plate mounted in an Instron Universal Test Machine.

A force probe was installed in a 1000 lbs. load cell in the Instron crosshead. A high potential DC current supply was used to apply 500 Vdc to the test sample. The probe was applied to the test sample with a crosshead speed of 0.05 in/min until breakdown voltage occurred. The applied load at breakdown was read from the chart recorder.

Probe Design:

Round metal probe machined to a 0.060-inch radius and electrically insulated with phenolic resin core material. Contact length is 0.5 inch.
