PURPOSE:To obtain a novel sliding member composition having improved self- lubricating properties and wear resistance, causing no sound in sliding, containing polyacetal, a specific polyethylene and an electrical conductivity imparter such as ketjenblack, etc., in a specific ratio. CONSTITUTION:(A) The aimed sliding member composition consisting of (A) 95-60wt% polyacetal, (B) 2-30wt% polyethylene having >=10 melt index and (C) 3-10wt% electrical conductivity imparter such as ketjenblack, etc. EFFECT:Has low friction and small variability in coefficient of friction. |
