My experience with foam has been figure out your required properties and call your part manufacturer or material supplier. You can get a bazillion foams off matweb but your supplier may not want to stock them etc. Figure our chemical resistance, flammability, color, density/hardness etc. and talk to whomever you have previous experience with purchasing from. If they can't come up with a solution then you go with something like matweb.

If you are doing composite glass foam work then it usually is urethane or PVC or styrofoam. urethane is usually 2lb/ft3(30kg/m3) and is non-structural or good for making surfboards.

PVC is the main structural foam and ranges from 45kg/m3 to about 250kg/m3, where its just about harder than wood. Contact a glass/resin/foam supplier for tecnical info.

We use a lot of 4# polyurethane because it can be UL 94 V-0 and is readily available.
