This is a little off topic but this is the group that might know.
We have been using Medex for casework, as well as a board called Arreis from Sierra Pine. www.sierrapine.com/Media/ArreisSpec041508wAd.pdf We've got a show coming in with some fairly strict specs so I wanted to check with others to see if they had used Arreis and if any testing had been done. We appreciate any help you can give us on this.

This is a major topic for us. We have to Marvel Seal all exposed wood and then cover with an approved fabric. We are trying to find a deck material that is easily jointed, paints well, cost effective and passes conservation. If anyone has any suggestions please let know.

We just had a similar issue with a traveling exhibit of Greek vases etc that required a fully sealed ped. We ended up using Komatex (sp?) which is like a PVC material for all our inserts and build ups. It worked great for all your concerns and comes in 3/4" sheets. I can give more info on the material if you think this may work for you.

This is for a show of historic books and documents (15th C.). There are no metals in the show and I don't believe there are any other sensitive materials present. This material has been generally regarded as safe by our conservation staff but I just was looking for additional information. If we are to substitute, the material needs to be as structurally appropriate as the other.

I have been making our book mounts out of plexy that I heat form to the opening angle that our paper conservator determines. Then I screw the plexy to a wedge (15degs. Or less) made of 9lb ethafoam. The entire mount is covered with fabric that matches the deck.

formaldehyde is not your problem. see: http://cool.conservation-us.org/coolaic/jaic/articles/jaic44-03-002_3.html
That is the sort of info I was looking for. The Formaldehyde hadn't been my main concern but the link to Formic acid production was very interesting. Getting the fabricators to change casework construction practices is slow but this helps.
