Where can I buy Aerogel? - Eng-Tips

OK I guess I'm half joking, or maybe only 25% joking...but has Aerogel gotten to the point where it's anywhere near reasonable as an industrial insulator yet? Does anyone sell it? Aspen, I think, tried to sell it to me for marine exhaust insulation a couple of years ago. The small sample I got demonstrated that it's flexible enough to conform to compound curved surfaces, and that it drops a fair amount of very fine ceramic dust when you handle it.

The dust made it a non-starter for me; engines don't like dust, and there's no way to encapsulate the aerogel that will reliably withstand exhaust heat.

The other non-starter; they never came back with a price for a sheet of the stuff; they just kept dancing around the issue. Too bad for them; yacht owners will pay big bucks for high tech.

Pembroke Pines, FL, USA I've met guys who wouldn't blink at that price.

.. and I just figured out how to encapsulate the stuff, but not in a way that would allow them to show it off. Sigh.
