PURPOSE:To provide a resin compsn. which is lowly frictional, has excellent resistance to wear and heat and is suitable for use as a sliding material, containing polytetramethyleneadipamide, powdered polytetrafluoroethylene and a filler. CONSTITUTION:100pts.wt. mixture of 60-98wt% polytetramethyleneadipamide (nylon 4,6) (A) having a relative viscosity of not lower than 1.5 (30 deg.C, in 97wt% sulfuric acid, a concn. of 10<-2>g/ml) and 40-2wt% powdered polytetrafluoroethylene (B) having an average particle size of not larger than 15mum is optionally blended with 0-60wt% filler (C) (e.g., calcium titanate whisk er) and a lubricant, a pigment, a flame retarder, an antioxidant, a stabilizer, an antistatic agent, etc. (D). |
