摘要： A phenol resin composition for forming pulleys used in motor vehicles is disclosed. The composition comprises 35 to 45 wt % of resol, 35 to 45 wt % of glass fiber, 5 to 15 wt % of one or more inorganic powders selected from the group consisting of calcium carbonate, clay, and wallastonite, and 1 to 3 wt % of polyvinyl butyral. The phenol resin pulley for motor vehicles is almost free from swelling or shell cracking on the surface at a high temperature of 250° C. or more and exhibits high mechanical strength and superior thermal shock resistance.
