Abstract
A non-sticking sliding part molding Composition comprising a mixture of a fluororesin and a thermoplastic resin other than fluororesin and a fibrous filler, said mixture and said fibrous filler accounting for 70 to 95 weight % and 5 to 30 weight %, respectively, and said thermoplastic resin other than fluororesin occurring in a proportion of 60 to 100 parts by weight based on t00 parts by weight of said fluororesin. The object is to provide a non-sticking sliding part molding composition which is not only fully possessed of the fundamental properties required of sliding parts but also has a well-balanced assortment of hardness, deflection under load, creep resistance, slidability, moldability, and toner-repellent property, thus surpassing the prior art.
