Patent

CA 2060898

2060898 9100180 PCTABS00003 A thin, multilayered rubber article (20) and method of making it, having greater resistance to the leakage of fluids therethrough, despite repeated stretching and relaxing of the article within range of movement. The article exhibits a ''self-healing'' property to impede fluid leakage despite preexisting, or later formed, pinholes or other small openings through the layers. In the method, the base layer (17) is initially stretched before applying an intimately adhered, thinner overlayer (18) of elastomeric material, thereby to provide a stressed interface between the two adhered layers. Additional overlayers (19) can be applied.
