Abstract
Solid lubricant-dispensing plastics containing: polyethylene with a molecular weight of about 200-700,000; an oil; an optional compatibilizing agent for the oil; and, a bleed control agent that controls the rate of release of the oil. Methods are also disclosed for preparing the lubricant-dispensing plastics that have controlled oil release rates that are dependent upon the amount of the bleed control agent, and are adjustable by changing oil viscosity and the initial amount of the oil in the formulation.
