Collection Risks

AIC Wiki - British Museum -2013 -Oddy test - pass for permanent use Any plasticizers and stabilizers may phase separate and ooze from polymer resulting in the formation of an oily film, white bloom on the surface of the material. This coating may corrode metal or transfer to objects nearby. Greg Smith and Michael Samide report that some rigid, unplasticized PVC construction boards give off a sulfur containing heat stabilizer (2-ethylhexyl thioglycolate [2-EHTG]) that can tarnish silver (publication forthcoming). However, they also reported finding several specific brands of PVC construction board, namely Komacel (Kommerling) and e-PVC (3A Composites) are safe for use in exhibition casework as they do not contain 2-EHTG.
