A two component polyoxymethylene based system is disclosed. The two component system is comprised of a first polymer layer and a second polymer layer. The first polymer layer is comprised of a polyoxymethylene polymer composition comprising a polyoxymethylene polymer and optionally a tribological modifier. The second polymer layer is comprised of a second polymer composition comprising a liquid crystalline polymer, a polyarylene sulfide polymer, or a combination thereof and at least one tribological modifier. The compositions provide polymer articles, such as conveyor components, with improved tribological properties.
