3M tapes

From: John E. Simmons <jsimmons<-a>

Our exhibits director has asked about using two different types of
3M tape inside an exhibit that he is constructing.  The two tapes
are a 3M 4462 double-coated polyethylene foam tape (closed cell
cross-linked polyethylene foam) with acrylic adhesive; and 3M
4432-4416-4408 closed cell polyvinyl chloride foam tape.  Looking at
the technical data for these tapes, I presume that the polyvinyl
tape is likely to off-gas as it deteriorates, but what about the
polyethylene foam tape with acrylic adhesive?
