say dry silicaWhat do they use in black boxes as insulating material?

Please do not say dry silica / aluminium / tungsten / S_steel. Im looking to insulate electronics from harsh temperature environments and it is crucial to find a light weight, insulating material.

Aerogel is probably the best material fulfilling all your requirements. You can buy it, but maybe not so easily
