Abstract
This invention provides a foam barrier which prevents substantial migration of plasticizer from a plasticized polymeric article, such as a PVC cable jacket, into a gel sealing material in contact with the article and prevents substantial migration of oil from the gel material into the article while not significantly interfering with the sealing contact between the gel material and the surface of the article.
