Physical Properties

I’ve been looking around for quite awhile now looking for a way to set a physical property for an entity.
I’ve found http://wiki.garrysmod.com/page/PhysObj/SetMaterial but the problem is there is nothing listing all the strings. Is it possible to use that to make an entity super bouncy? Or do I have to use a different method?
EDIT: Found the table. But it doesn’t list super bouncy? Anyways for you guys if you have this problem:
