When Thor opened the Iris of Nidavellir's forge, he got 3rd degree burns. The heat he was exposed to was able to melt Uru. And, yet, his clothes survived.

Thor Opening Iris of Stormbreaker Forge

How? Thor definitely doesn't have aura kind of protection like silver age Superman as observed from Thor: Ragnarok movie.

What material Thor's clothes are made of?

    It's a rare-known material called "The-filmmakers-had-to-do-it-this-way-otherwise-you-would-have-had-a-bare-naked-man-in-an-otherwise-nudity-free-movie-just-accept-it-as-it-is-ium".

    In the comics, super costumes are made of unstable molecules, a substance invented by Reed Richards. They can stretch along with Mr Fantastic, turn invisible along with Invisible Girl, and they don't burn when the Human Torch flames on. Any time a costume isn't destroyed, just assume it's unstable molecules. links: 1) spiderman.fandom.com/wiki/Unstable_Molecules / 2) marvel.fandom.com/wiki/Unstable_Molecules
