Abstract
A tribologically modified ultrahigh molecular weight polyethylene (UHMW-PE) polymer composition is disclosed. The UHMW-PE polymer composition is comprised of an UHMW-PE polymer and at least one tribological modifier. The tribological modifier may be comprised of a silicone powder, a silicone oil, an olefin oligomer, an ultrahigh molecular weight silicone, or any combination thereof. The composition and polymer article produced therefrom may exhibit improved tribological properties, such as a reduced coefficient of friction and low wear, when contacted against a counter-material in comparison to an unmodified UHMW-PE polymer composition.
