Abstract
A plastic conveyor chain includes a multiplicity of pinned links each having a flat load-carrying portion formed from a synthetic resin compound containing a polyacetal resin and a silicone-containing lubricant. Preferably, the silicone-containing lubricant contains, with respect to the weight of the synthetic resin compound, 0.5 to 2.0% by weight of silicone oil, 0.5 to 2.0% by weight of potassium titanate fiber, and 0.5 to 2.0% by weight of fatty ester obtained from a monobasic fatty acid and a monohydric alcohol. The thus formed flat load-carrying portion has a low friction coefficient such that the conveyor chain can achieve stable conveyance of articles even when the articles have an unstable bottom configuration.
