Asbestos replacement in aircraft

I think Peter is reffering to the thick (1″) lagging that they used on fusalage internal piping, forgive if I’m mistaken though!
This was made up as a very thick paste (usually the worst form of asbestos) and then spread over the pipe, it dried to form a thick layer of insulation. I have never seen a modern equivelent to this, however preformed foil backed fibreglass, or other more modern materials, including mineral based and armaflex pipe lagging, heavily painted over in PVC (ET-10) paint should give a very similar look.

I’ve never seen aircraft engine exhausts insulated though.

We used exhaust wrap from Demon Tweeks on a flying P-47,so it’s well up to the job.

If it’s not for air use how about using the exhaust wrap that we use on race car manifolds?
It looks pretty much the same as asbestos, but without the associated hazzards.
Something like this?

(its also available on ebay, often cheaper)

On some radials I’ve seen woven glass fiber used to insulate the exhaust stacks. Think it was on an A26 so that would be 2800’s.

Thanks Bloodnok. This is for a staic ground running aircraft. They just want it to look authentic without the health risks.

When i tinkered with C130’s for a living we had a mods program to replace all the asbestos pads where the bleed air pipes touch the airframe. So a modern equivelant is available, it’s just a case of finding out what it’s called and where to get it from…
