TflexTM HD300 Series Thermal Gap Filler PRODUCT DESCRIPTION Laird TflexTM HD300 is a 2.7 W/mK gap filler material in Laird’s high deflection line of products. Tflex HD300 is an excellent choice when wide manufacturing tolerances occur as variable gaps can be filled with Tflex HD300 while generating minimal board and component stress. Laird’s unique manufacturing capabilities, and filler and resin knowledge result in this unique product designed with customer applications in mind. Tflex HD300 material exhibits excellent surface wetting characteristics and high deflection properties ensuring low contact resistances and providing an overall lower total thermal resistance. A Tgard™ liner at one side option is provided to form into Tflex HD300TG, offer guaranteed >6KV AC dielectric barrier, is cut-through resistant and enables easy non-tacky handling at one side. A Tgard™ liner in the middle option is provided to form into Tflex HD300MTG for 40mil and above thicknesses, offer guaranteed >6KV AC dielectric barrier, has cut-through resistant and two-sided tackiness. FEATURES AND BENEFITS • • • • • • 2.7 W/m K thermal conductivity Low pressure versus deflection characteristics Excellent surface wetting for low contact resistance Minimizes board and component stress.
