Potting compond

The Wacker ELASTOSIL® RT 675 A/B potting compound has amazing heat transfer properties:



Thermal conductivity: 1,2 W/m×K.

Some comparisons:

Copper: 401W/m*K.

Pure aluminium: 237W/m*K.

Normal aluminium: 100W/m*K.

Air: 0,0025W/m*K

This silicone compound is in other words 480 times better

than air or 100 times worse than solid aluminium.

We may want to use this as a partial fill for the new products with lots of SMD switches, it will make heat transfer much simpler.

It is sold by Elfa in sweden, article number 80-852-84.
