Thermal Gap Fillers


Tflex HD30000BLDC1 Series

Laird Tflex™ HD30000BLDC1 is a 2.8 W/mK gap filling material in our high deflection line of products. It is an excellent choice when wide manufacturing tolerances occur. These variable gaps can be filled with Tflex™ HD30000BLDC1 while generating minimal board and component stress. Laird’s unique manufacturing capabilities, filler and resin knowledge result in this unique product designed with customer applications in mind.
Tflex™ HD30000BLDC1 is designed for applications that require black material for aesthetics or visual contrast. Laird’s tack eliminating DC1 coating allowing ease of handling and easy rework.
While achieving its stellar compliancy, Tflex™ HD30000BLDC1 does not sacrifice its overall thermal performance. With a thermal conductivity of 2.8 W/mK, low thermal resistances can be achieved at low pressures. All of this results in an excellent product for handsets and other portable applications.
