?共聚組分為氧化乙烯-CH2CH2O-，再加一個碳元素。盡管共聚比例不同，但可以說共聚甲醛的性質是通過在甲醛均聚物中加入環氧乙烷聚合物而形成的。在短期力學性能方面，均聚物往往比共聚物高，但在長期力學性能方面，共聚物的下降幅度小于均聚物。此外，還添加了聚四氟乙烯（PTFE）。有些性能變化，稍軟，較不硬，比純聚甲醛樹脂更滑。與純聚甲醛板相比，該材料具有更好的潤滑性。POM-H+PTFE軸承摩擦系數中等，耐磨性好，幾乎沒有爬行現象。甲醛共聚是三甲基甲醛與少量二惡烷共聚的產物。正是由于結構上的差異，導致了甲醛在各種性質上的均聚和共聚的差異。與甲醛均聚物相比，甲醛共聚合的密度、結晶度、熔點和強度較低，但熱穩定性相對較好，不易分解，加工溫度范圍較寬（30～50℃），且 。以上文獻若需轉載請備注出處：PBT樹脂 //shanglikaiguan.cn/
