Actual application performance is directly related to the surface roughness, flatness and pressure applied. Typical Applications Include: * Power supplies * Power semiconductors * Automotive electronics * Motor controls Configurations Available: * Sheet form, die-cut parts and roll form; with or without pressure sensitive adhesive Building a Part Number - AC - 12/250 - Standard Options NA Section E 0.007 Section D - Section C Section A SP400 Section B 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 fiberglass provides excellent cut-through resistance. In addition, Sil-Pad 400 is non-toxic and resists damage from cleaning agents. TEST METHOD Visual Reinforcement Carrier Tensile Strength (psi) / (MPa) Sil-Pad 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-Pad 400 is to electrically isolate power sources from heat sinks.
