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
鏗乥erglass. It is specially 鏗乴led and offers low thermal resistance.
Sil-Pad 1000 is non-toxic and resists damage from cleaning
agents. It is 鏗俛me 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
Sil-Pad 2000 is Bergquist鈥檚 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 鏗乴led to
maximize the thermal and dielectric performance of the 鏗乴ler /
binder matrix. The result is a 鈥済rease-free鈥? 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".
