If they are talking about coolant it might be similar to the Ferrari graphene coolant.
the thing is with flexegraph they only talk about its conductivity, which means that it absorbs or gives off heat faster, so you can flow it faster. What Andy Cowell was saying is they've raised the coolant temperature, in order to have a bigger temperature gradient in the radiator between water and air, and give off more heat that way. And he said they've raised it so high the aluminium in the engine is degrading and they've had to work at it to get it to do 8 races. Or perhaps by the sound of it even that is getting a bit sketchy
Looking around it seems 150C is about where the degradation starts to kick in as @godlameroso was saying, and perhaps they're a bit above that. And they can't do that with pure water at 3.75 bar, which boils at 141, they must have had to add something to raise the boiling point, and most things that do that seem to reduce the specific heat, working the wrong way. Also additives can raise the viscosity meaning bigger tubes and/or pumping losses
so it must be rather cunning! It might be Flexegraph like Ferrari but so far i'm not seeing nanoparticles of graphene raising the boiling point, so i'm suspecting something else, that's new and secret
Also they should've listened to me and AM'd it in steel like i was saying
