Tflex™ HP34 Thermal Gap Filler

Laird Tflex™ HP34 Thermal Gap Filler is a silicone-free, high-performance gap filler made of aligned graphite fibers that provide an alternative to messy grease gap fillers. The graphite fibers are aligned to provide high bulk thermal conductivity of 34W/mK. In addition, the Tflex HP34 series is designed to maintain its thermal performance within an application under increased pressure. The ideal performance will occur in the lower pressure range of 10psi to 30psi. Laird Tflex HP34 Thermal Gap Filler also offers low contact resistance to the mating surfaces.
