Small nit, but TEATEB isn't hypergolic, it's pyrophoric.
Hypergolic indicates when when two propellants (a fuel and an oxidizer) come in contact with each other, they ignite spontaneously.
Pyrophoric indicates that the fuel ignites when it contacts air (no oxidizer needed in a normal Earth atmosphere).
- vvanders 6y agoIt's listed as one of the more common[1] hypergolic propellants with LOX, pyrophoric is pretty much a superset of hypergolic(just that earth air brings the oxidizer "for free").

- foota 6y agoI believe you mean subset, yes? In that some subset of hypergolic materials have a component of air as their oxidizer and are therefore pyrophoric.
