摘要:
The sliding material is obtainable by extrusion of a raw material containing an olefin-based polymer and a silicone compound as the essential components. A part of the olefin-based polymer forms a crosslinked material in the sliding material. The crosslinked material forms domains to disperse in the sliding material so as to prevent uneven distribution of the silicone compound in the extrusion direction. The residual fraction of hot xylene reflux of the sliding material is in a range from 33 to 75% by weight based on the total weight of the sliding material, and the content of the silicone compound based on the total weight of the sliding material is in a range from 5 to 35% by weight.
