PURPOSE:To obtain a plastic molded article useful as rotary parts or sliding parts, by forming an infiltrated layer of an aqueous dispersion of fluorine- contained resin in the interior of a plastic molded article on the surface side. CONSTITUTION:An aqueous dispersion of a fluorine-contained resin (preferably containing wax and/or silicone as well as the fluorine-contained resin) is brought into contact with the interior of a plastic molded article such as rotary parts, sliding parts, etc. on the surface side, so that an infiltrated layer having >=5mu (preferably >=20mu) is formed on the interior of the molded article on the surface side. The aqueous dispersion of the fluorine-contained resin attached to the surface of the molded article is removed by washing or wiping out, to give the aimed molded article. The contact treatment is preferably carried out under reduced pressure at <=80 deg.C. |
