HIGH PERFORMANCE
Sil-Pad 1000®, Sil-Pad 1500® and Sil-Pad 2000®
SIL-PAD 1000
Sil-Pad 1000 has the same excellent mechanical and
physical characteristics of our Sil-Pad 400 material while
offering a 35% reduction in thermal resistance.
Sil-Pad 1000 is a composite of silicone rubber and
fiberglass. It is specially filled and offers low thermal resistance.
Sil-Pad 1000 is non-toxic and resists damage from cleaning
agents. It is flame retardant and specially formulated for use as a
thermally conductive insulator.
SIL-PAD 1500
Sil-Pad 1500 is an economical, high performance insulator
with a thickness between that of Sil-Pad 1000 and Sil-Pad 2000.
SIL-PAD 2000
Die-Cut parts, Rolls and Sheets
Sil-Pad 2000 is Bergquist’s high performance, high
reliability thermally conductive insulator. Sil-Pad 2000 is
designed for demanding military / aerospace and commercial
applications. In these applications, Sil-Pad 2000 complies with
military standards. This silicone elastomer is specially filled to
maximize the thermal and dielectric performance of the filler /
binder matrix. The result is a “grease-free”, conformable material
capable of meeting or exceeding the thermal and electrical
requirements of high reliability electronic packaging applications.
Sil-Pad 2000 is also available in thicknesses from .010" to .060".
Sil-Pad 1000, 1500 and 2000 are available in die-cut parts
and sheets (6" x 6" min., 6" x 12", 8" x 8", 10" x 10" and 12" x
12"). Only Sil-Pad 1000 and 1500 are available in roll form.
