[Nhcoll-l] longterm stability of Instapak Foam

[Pellegrini, Rodrigo]

I'm sure there are other list members that know materials better than I, but my understanding is Polyethylene (PE) foam is much more stable than PU. The system you describe would probably work well enough with PE foam, which would last much longer IIRC.
You might also wish to review a copy of "Supporting Old Bones, Storage Jackets for Oversize Dinosaur Bones" by Fox, Marilyn, and Vicki Fitzgerald of the Yale Peabody Museum of Natural History. This was a poster presented at the Society for the Preservation of Natural History Collections (SPNHC) Annual Meeting in 2012, Special Poster Session: Storage Techniques for Arts, Science, and Humanities Collections.
I can forward a copy by private email if you don't have it in your library.

Best regards,

Rod

Subject: [Nhcoll-l] longterm stability of Instapak Foam

Hi there,

we at the paleo vertebrate department of the MfN Berlin need to pack heavy and big dinosaur bones and are considering using instapak foam (or any other PU foam) inside a plaster casket. So I was wondering if anyone has some experience with it and if the foam is stable in the long term or if there are any other risks of outgassing or anything else. I know it is sensible to UV light, but as it is in an enclosed casket I would have hoped that shouldn't pose to much of a problem.
I am also interested and open in/to any other idea concering the the storage of big fossil specimen.

Thanks and all the best
Thomas
