Nitrile Rubbers and Vinyl Polymer Mixtures

Abstract

Abstract The outstanding resistance to abrasion, oil, fire and ozone of vulcanized nitrile rubber/PVC blends has stimulated cable manufacturers throughout the world. In this paper the effect of polymer properties on mixing conditions is discussed and physical properties resulting from different mixing conditions reviewed. The physical (including electrical) properties of vulcanized and unvulcanized nitrile rubber/ PVC blends are related to the use of these blends in covering electric cables. Comparisons are made with other types of sheathing and insulating materials and existing potential uses of nitrile rubber/PVC blends in cable coverings are discussed.
