Product Description

Laird Tflex 300, at pressures of 50psi, will deflect to over 50% the original thickness. This high rate of compliancy allows the material to totally blanket the component, enhancing thermal transfer. The material has a very low compression set enabling the pad to be reused many times. Tflex 300, in achieving its stellar compliancy, does not sacrifice thermal performance. With a thermal conductivity of 1.2 W/mK, low thermal resistances can be achieved at low pressures. Tflex 300-H is offered with a hard, metallized liner option for easy handling and improved rework. The metallized liner lower coefficient of friction also allows for easy assembly of parts that must slide together, such as a card into a chassis.

    I'm glad that I've researched further into custom cables for my Cooler Master MWE Gold 850 v2! Almost went for CableMod to get my custom cables, but Moddiy seemed more reliable from the reviews I've read!

    Good product, but a bit expensive! I'll use these phase-change thermal pads replacing the old OEM ones of some of my devices (GPU,M2 nvme, Steam Deck and other things). All in all, very good seller. I recommend it.
