Tflex™ HD7.5

Silicone based Thermal Gap Filler

Product Description

Laird’s Tflex™ HD7.5 gap filler is a new developed very soft  silicone material in our high deflection series.  With a thermal conductivity of 7.5W/ mk, Tflex™ HD7.5 is designed to provide superior pressure versus deflection characteristics.  The material will provide minimal stress on components during application while maintaining low thermal resistance.  As a result, less mechanical and thermal stresses will be experienced within your device.
