Aerogel (ARGL or AEGL) block temperature (similar to insulator), fire, and plasma. But crumbles under the smallest amount of pressure, dissolves in water and acid, and melts in lava
Aerographene (ARGR or AEGR) is like aerogel (blocks temp, fire, and plasma) but way more resistant to pressure, doesn't melt in lava, and conducts electricity. But still dissolves in water and acid like aerogel
ARGL can't be resistant to FIRE or PLSM, because both elements emit pressure.
simple solution: make the pressure threshold high enought to withstand fire and plasma, but low enough to break under pressure
Aerogel seems kind of useless to me. We already have SHLD which blocks temperature, fire, and plasma while also having some pressure resistance.
Aerographene sounds really cool though as it is an electrical conductor.
SHLD is destroyed under a pressure of 64; easily destroyed by nuclear bombs.
