can this be cut with hot wire ?

Yes, but it is high density. It will not cut as easily as Styrofoam

Does this require moisture to cure?

This will not cure with moisture present.

whats the difference between 2#,4# & 6#? is the polyurethane hydrophobic or hydrophilic?

To clarify, each density of foam has a different expansion rate, so they are all used for different applications. Please refer to the reference chart of each listing for details regarding expansion. This material is hydrophobic. -FSD
