Abstract
An ionomeric modified poly-ether-ester plastic material combined with a small amount of silica is used as a substitute for the conventional uses of polyvinylchloride in such applications as tubing for medical applications, for bags and other medical containers, for tubing in food processing and as sheets and films for bacterial and virus exclusion. The ionomeric modified poly-ether-ester has various advantages which make it particularly suitable for such uses. The silica may be in the form of colloidal silica dioxide or silica oil.
