It kind of sounds a little like that. It is a silica based insulation ( think quartz ) that until recently was very expensive to make. It appears the Cabot has learned how to make it under ambient conditions that allow for continuous manufacturing and control of many of it's properties. Here
is another article about it (scroll about half way down the page.)
