BERGQUIST SIL PAD TSP 900 is a composite of silicone
rubber and fiberglass. The material is flame retardant and is
specially formulated for use as a thermally conductive insulator
. The primary use for BERGQUIST SIL PAD TSP 900 is to
electrically isolate power sources from heat sinks.
BERGQUIST SIL PAD TSP 900 has excellent mechanical and
physical characteristics. Surfaces are pliable and allow
complete surface contact with excellent heat dissipation.
BERGQUIST SIL PAD TSP 900 actually improves its thermal
resistance with age. The reinforcing fiberglass provides
excellent cut-through resistance. In addition, BERGQUIST SIL
PAD TSP 900 is non-toxic and resists damage from cleaning
agents.
