Thermally Conductive,Unreinforced Gap Filling Material Features and Benefits

TYPICAL PROPERTIES OF GAP PAD 1500 • Thermal conductivity:1.5 W/m-K• Unreinforced construction for additionalcompliancy• Conformable,low hardness • Electrically isolating Gap Pad 1500 has an ideal filler blend thatgives it a low-modulus characteristic that maintains optimal thermal performance yet still allows for easy handling.The natural tack on both sides of the material allows for good compliance to adjacent surfaces of components,minimizing interfacial resistance.
