Sil-PadŽ is a thermally-conductive interface material developed for the electronics industry.
This flexible silicone material is designed to conduct heat away from
discrete components or circuit board assemblies into a heat sink,
heat spreader, or equipment chassis.
Sil-PadŽ 400 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 Sil-PadŽ 400 is to electrically isolate power sources from heat sinks.
Sil-PadŽ 400 has excellent mechanical and physical characteristics.
Surfaces are pliable and allow complete surface contact with excellent heat dissipation.
Sil-PadŽ 400 actually improves its thermal resistance with age.
The reinforcing fiberglass provides excellent cut-through resistance.
Sil-PadŽ 400 is non-toxic and resists damage from cleaning agents.
Typical Applications Include:
Sil-PadŽ thermally conductive insulators, in their many forms,
continue to be a clean and efficient alternative to mica,
ceramics or grease for a wide range of electronic applications.
Excellent thermal performance
Eliminates the mess of grease
More durable than mica
Efficient "total applied cost" that compares favorably with other alternatives.
