摘要： A polyacetal composition is provided for use in plastic-plastic wear applications, said composition containing about 85 to 99 weight percent polyacetal, about 0 to 5 weight percent polytetrafluoroethylene fibers, about 0.5 to 5 weight percent ethylene methyl acrylate copolymer, and about 0.5 to 5 weight percent of at least one lubricant. The compositions are particularly useful in forming shaped articles for use especially in conveyor chain applications and gear applications.
