Abstract
Abstract An adhesive bandage composition uses a blend of polyisobutylene, polybutene, butyl rubber with reinforcing fiber, filler material and zinc oxide blended under heat and rolled into a thin sheet. The sheet of adhesive material can be attached to a bandage material on one side and covered with a protective paper on the other and cut to shape for application to a body surface.
