If oxygen plays a part in the degradation of the foam, then storing
the items in an oxygen-free microclimate would slow or halt the
changes. Mitsubishi Gas Chemical makes a transparent high-barrier
film (Escal) and an oxygen scavenger that does not change the
moisture levels in the microclimate (RP-K type). Storing the items
in sealed bags would also protect nearby artifacts from off gassed
degradation by-products--RP will also trap many corrosive gases.

My late uncle once purchased, in a fit of visionary inventory
acquisition, hundreds of yards of printed vinyl backed with black
foam and fabric. I believe the material was purchased for making
"go-go boot slippers" but he chickened out, or the market changed,
and the footwear was never made. I quietly "liberated" a number of
rolls from his stock room. The vinyl was printed with garish black
and white swirls, and the rolls were about 44 inches wide--they made
amazing curtain walls and light traps for my darkrooms--truly very
sixties, but then so was I at one time.
