SIL-PAD 400
is a composite of silicone rubber and fiberglass. It is flame
retardant and is specially formulated for use as a thermally
conductive insulator. Primary use is to electrically isolate
power sources from heat sinks.
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 fiberglass gives excellent cut-through resistance
and Sil-Pad 400 is non-toxic and resists damage from
cleaning agents.
ingredients to provide higher thermal performance. This
material has similar physical characteristics of the Sil-Pad
400 material with enhanced thermal performance.
