POM'smarketprospects:First,productionisbecomingmorecentralizedandmonopolized.TheproductioncapacityofHurst-Celanese,DuPont,BasfandMitsubishiGasaccountsfor83%oftheglobalPOMproductioncapacity.ThesecompaniescontroltheproductionandmarketoftheworldPOManddominatethefateoftheworldPOM.Second,Asiaisdevelopingrapidly,andthec***umptionofPOMisincreasingrapidly.Before1995,about92%oftheworld'sPOMproductionfacilitieswerelocatedinKorea,Europe,andotherindustrialdevelopedcountriesandregi***.From1997to2004,thecapacityofnewinstallati***inAsia,especiallyinJapan,andTaiwan,China,reached168,000t***.WiththeincreaseofSingapore,Asia'snewcapacityaccountedfortheproportion.About66%oftheworld'snewlyaddedcapacity.POM产品系列：标准级冲击改良级（添加橡胶，弹性体）矿物填充级（低翘曲尺寸稳定级）玻纤增强级（强度、刚度、硬度、蠕变强度）耐候级低磨耗级：耐热降低导电防静电级低气味级低摸垢级高润滑POM：在POM中加入石墨、F4、二硫化钼、润滑油及低分子量PE等，可提高其润滑性能。例如，在POM中加入5份F4，可降低摩擦因数60%，耐磨性提高1～2倍。再如，在POM中加入液体润滑油，可大幅度提高耐磨性和极限PV值。为提高由油的分散效果，需加入炭黑、氢氧化铝***钡、乙丙橡胶等吸油载体。加入5%油POM的摩擦性提高72%，极限PV值可达3.9MPa·m/s（纯POM为0.213MPa·m/s），为其他工程塑料的3～20倍。)
