Abstract
The invention is a concurrently sintered and cross-linked ram extruded product formed by a mixture of an ultra high molecular weight polyethylene powder with a cross-linking agent, an electrically conductive agent and a lubricant. As little as 0.5 parts per 100 parts of polyethylene of the electrically conductive agent added to the ultra high molecular weight polyethylene powder coats the power to provide adequate conductivity without adversely affecting the mechanical properties of the product.
