Thermene launched a new product based on graphene - the Thermene Graphene Thermal Paste is based on graphene-oxide flakes and is aimed towards CPU cooling. The company just started selling this new product a few days ago. For $20 you can buy 3 ml of Thermene which should be enough for about a dozen CPUs.
Thermene is easy to use - it comes with a simple paint brush and you simply apply it to your CPU surface. The material takes 10 hours to cure.
The company says that the material is 50% advanced thermal base, 50% fluid-suspended graphene nano-particles at a high purity of at least 80%. We were told that the graphene supplier is Graphene Supermarket. Specifically they are using graphene oxide flakes (or platelets) which is at least 80% one layer graphene.
