PURPOSE:To obtain a resin form with outstanding sliding characteristics, by immersing in a lubricant oil a form produced by incorporating a synthetic resin with ultra-high-molecular weight polyethylene to allow said lubricating oil to be absorbed into said polyethylene to reduce the coefficient of friction on the surface layer of said form. CONSTITUTION:A form produced by incorporating (A) 100pts.wt. of a synthetic resin (e.g. polyacetal resin, nylon-6) with (B) 1-30(pref. 3-10)pts.wt. of ultra- high-molecular weight polyethylene (e.g. with an average molecular weight determined by the viscosity-averaging method being >=1,000,000, such molecular weight by light scattering method >=3,000,000, and particle size of 30-200mum, its SP value being 7, 9) is immersed in a lubricating oil to allow said oil to be absorbed into said polyethylene to provide the form with sliding characteristics. |
