I was thinking about getting even lighter Kevlar string for shock cords in little BT-20 and below rockets. There's some discussion of how Kevlar isn't really all that flame resistant. It occurred to me, why not use heavy-ish Nomex thread?
This link doesn't have anything above Tex 90, and I'm not sure how robust that is. https://www.ebay.com/itm/194186823903?var=495278032678
This one has some Tex 200: https://www.ebay.com/itm/115794536998
I'm talking about 13mm powered stuff here, mostly BT-5 and BT-20, possibly a BT-50 if I'm trying to keep it really light. Not anything bigger. At least the thread is cheap. It might hold knots better than Kevlar and/or have its strength reduced less by having knots tied in it. For <$10, I might just get some to try it.
Any experts on its characteristics and use?
