<p>[QUOTE=&quot;desertgem, post: 1974082, member: 15199&quot;]No, PVC is the plastic matrix, <b>plasticizers </b>such as phthalate esters or acid linked components are between the plastic units to provide the flexibility. Without plasticizers, PVC is hard ( such as white pvc pipe) and doesn&#039;t damage unless it is heated way above any normal coin storage temperature. The plasticizers tend over time to migrate to the surface and adsorb water to make an acidic goo , which when contacts metal ( such as coins) causes corrosive processes. The &#039;new shower curtain&quot; smell does occur with high level plasticizers ( usually chinese products) , but may not be noticed on the low level holders.[/QUOTE]</p><p><br /></p>
