ABSTRACT:
Self-lubricating polyacetal resin compositions and molded articles (e.g. "wear parts") formed thereof include a polyacetal base resin, and a self-lubricating effective amount of a silica powder in which a silicone polymer (e.g. silicone oil) is absorbed. The silica powder acts as a carrier for the silicone polymer so as to improve the dispersibility of the silicone polymer in the polyacetal base resin as well as to allow greater silicone polymer "loading" of the polyacetal base resin. As a result, improved lubricant dispersibility and sliding characteristics are achieved.
