1500°F / 815°C: Braided Vermiculite Coated Fiberglass Sleeve: Premium
Grade. Very High Temperature & Heat Resistant
FlameShield™ braided fiberglass sleeve with
specialty coating of Vermiculite.
Available in thin wall (1/16 in. / 1.6mm.) and
thick wall (1/8 in. / 3.18mm.).
1500°F / 815°C continuous exposure with
excursion to 2000°F / 1093°C.
1500°F / 815°C continuous rating, high insulation value & excellent personnel protection
The Vermiculite coating adds abrasion resistance and higher temperature capabilities which makes this sleeve a good
insulator for hose, cable and copper or aluminum tubing.
Dave Jersey: This is meant more for protection against accidental contact, think about the Internal Combustion Engine Exhaust, at 1500 f a mechanic can brush up against it
with little danger of serious burns ! It needs to survive higher temperatures to continue to function as a heat shield or barrier ! I personally doubt it would hold up in a R.M.H.
Heat Riser, and the largest size 5'', would make a marginally performing system due to friction loses in the laminar flow and turbulence !
I expect that it has been tried as a gasket material to help seal the type of 55 gal drums with removable tops, that should be a safe use with a wide enough heat range spread.
What we are looking for is something that will do a better job of resisting the transfer of heat energy though itself until the Temperatures are closer to 2500 - 3000 degrees f,
our combustion chamber should be glowing red hot and a small piece of dry wood dropped into the feed hole bursts into flame - a ceramic blanket material - Pricey!
