Laird Tflex HD400 is a 4.0 W/mK gap filling material in our high deflection line of products. Tflex
HD400 is an excellent choice when wide manufacturing tolerances occur. These variable gaps can be
filled with Tflex HD400 while generating minimal board and component stress. Laird’s unique
manufacturing capabilities, filler and resin knowledge result in this advanced product designed with
customer applications in mind.
Tflex HD400 is provided in thickness from 0.5mm (.020”) up to 5mm (0.200”) in 0.25mm (.020”)
increments as standard. In addition, Laird can provide Tflex HD400 in multiple converted formats
through approved converters and distribution networks.
