Tflex TM HD300 is a 2.7 W/mK gap filler material in Laird’s high deflection line of products. Tflex TM HD300 is an excellent choice when wide manufacturing tolerances occur as variable gaps canbe filled with Tflex TM 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 TM HD300 material exhibits excellent surface wetting characteristics and high deflection properties ensuring low contact resistances and providing an overall lower total thermal resistance. Tflex TM HD300 is provided in thickness from 0.5mm (.020”) up to 5mm (.200”) in 0.5mm (.020”) increments as standard. In addition, Laird can provide Tflex TM HD300 in multiple converted formats through approved converters and distribution networks.

FEATURES AND BENEFITS 

• 2.7 W/m K thermal conductivity
