It offers excellent thermal conductivity, is non-electrically conductive for safe use on sensitive electronics, and maintains stable performance after multiple thermal cycles. Designed to minimize pump-out effects, it ensures durable and efficient cooling for CPUs, GPUs, and other electronics. ## Description The phase-change material on which the PhaseSheet PTM is based is solid at room temperature. The material only begins to liquefy at temperatures above 45 degrees Celsius. A high contact pressure of around 300-400N is required for optimum distribution of the liquid PhaseSheet PTM and thus the lowest possible layer thickness. PhaseSheet PTM has a very low viscosity in its liquid state and contracts again when it changes to a solid material, thus minimizing the pump-out effect. The pump-out effect is particularly pronounced when combining a copper cooler on a graphics chip because silicon and copper have different linear expansion when heated. The temperatures under load cause the heatspreader and the base plate to deform (concave or convex) and return to their original shape (straight) when they cool down. As a result, the thermal paste is slowly pressed out between the heatspreader and the base plate of the CPU cooler, for example. Outstanding thermal conductivity Consistently high performance Very long service life Versatile in application Not electrically conductive Easy to use PhaseSheet PTM is more durable than traditional thermal pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. PhaseSheet PTM develops and stabilizes its maximum thermal conductivity after around ten thermal cycles above 60 degrees Celsius.
