The Original Fiberglass Based Sil-Pad
SIL-PAD 400
Sil-Pad 400 is the original Sil-Pad material. Sil-Pad 400
is a composite of silicone rubber and 鏗乥erglass. It is 鏗俛me
retardant and is specially formulated for use as a thermally
conductive insulator. Primary use is to electrically isolate
power sources from heat sinks.
Sil-Pad 400 has excellent mechanical and physical
characteristics. Surfaces are pliable and allow complete
surface contact with excellent heat dissipation. Sil-Pad 400
actually improves its thermal resistance with age. The
reinforcing 鏗乥erglass gives excellent cut-through resistance
and Sil-Pad 400 is non-toxic and resists damage from
cleaning agents.
SIL-PAD 600
Sil-Pad 600 is a silicone elastomer 鏗乴led with special
ingredients to provide higher thermal performance. This
material has similar physical characteristics of the Sil-Pad
400 material with enhanced thermal performance.
Special Thicknesses, Rolls and Sheets
Sil-Pad 400 can be supplied on special order in a variety
of thicknesses from .007 to .045 inches to ful鏗乴l special
requirements of insulation path minimums or other spacing
needs. Sil-Pad 400 and 600 are available in die-cut parts,
sheets (6" x 6" min., 6" x 12", 8" x 8", 10" x 10" and 12" x
12") and roll form.
