▎ 摘　　要

NOVELTY - A polymeric material mixture comprises a fluorine-containing polymer, a siloxane polymer, and at least two polymer processing additives having different chemistries. USE - Polymeric material mixture used for forming article e.g. pipe, tube, duct, channel and conduit for device (all claimed). Uses include but are not limited to telecommunications, electrical applications, medical applications, vehicular transportation, consumer products, construction, projectile barrels, missiles, rockets, trains and fluid transportation industries. ADVANTAGE - The polymer material mixture improves thermal stability and abrasion resistance of the articles. The articles have lower wear rates and reduced coefficient of friction of surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device, which comprises an article comprising a surface comprising the polymeric material mixture comprising (a) the fluorine-containing polymer or a graphene, (b) the siloxane polymer and (c) two polymer processing additives.
