We rocketeers are interested because this is what we use to keep ejection charges from melting/burning our shock tethers and parachutes. That and reusable Nomex, Kevlar, Nomex/Kevlar, or car airbag parachute protectors. Or both dog barf and a parachute protector. Or dog barf wrapped in Estes or Quest flameproof wadding. That's one of my current favorites for rockets <3" in diameter. Makes a flame resistant piston of sorts. Often recovered near the rocket. If recovered, often reusable (see photo below the video).
