Foam types and lifespan

[ReaderScars]

Does anyone work with foam, as in closed cell rather than shaving? I was wondering if anyone could advise me on the type of foam which would be used to create padding/padded compartments in bags for tech stuff - laptops, diagnostics/camera kit etc.

I know some foams degrade over time, so was wondering which foams can be laminated with fabric and still have a good balance of cost, weight and shelf life for these kind of applications?

Do a search for Plastazote.
