Simple application and perfect adjustment of the PhaseSheet
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 force of around 300-400 N is required for optimal 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. This mitigates the pump-out effect.

Optimal heat dissipation
The pump-out effect is particularly pronounced when a copper cooler is combined with a graphics chip because silicon and copper have different linear expansion rates when heated. The temperatures under load cause the heat spreader and the base plate to deform (concave or convex) and return to their original shape (straight) when they cool down. This causes the thermal paste to slowly be pressed out, for example, between the heat spreader and the base plate of the CPU cooler.

Durable and hard-wearing
PhaseSheet PTM is more durable than traditional thermal pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. The maximum thermal conductivity of the PhaseSheet PTM develops and stabilizes after around ten heat cycles of 60 degrees Celsius each.
