聚甲醛是一种没有侧链、高密度、高结晶性的线型聚合物，具有优异的综合性能。聚甲醛的拉伸强度可达70MPa，可在104℃下长期使用，脆化温度为-40℃，吸水性较小。但聚甲醛的热稳定性较差，耐候性较差，长期在大气中曝晒会老化。

聚甲醛的力学性能相当好，它具有较高的强度的弹性模量，摩擦系数小，耐磨性能好。聚甲醛还具有高度抗蠕变和应力松弛的能力。

聚甲醛尺寸稳定性好，吸水率很小，所以吸水率对其力学性能的影响可以不予考虑。聚甲醛有较好的介电性能，在很宽的频率和温度范围内，它的介电常数和介质损耗角正切值变化很小。

聚甲醛的耐热性较差，在成型温度下易降解放出皿醛，一般在造粒时加入稳定剂。若不受力，聚甲醛可在140℃下短期使用，其长期使用温度为85℃。

聚甲醛耐气候性较差，经大气老化后，一般性能均有所下降。但它的化学稳定性非常优越，特别是对有机溶剂，其尺寸变化和力学性能的降低都很少。但对强酸和强氧化剂如硝酸、硫酸等耐蚀性很差。

聚甲醛的拉伸强度达70MPa，吸水性小，尺寸稳定，有光泽，这些性能都比尼龙好，聚甲醛为高度结晶的树脂，在热塑性树脂中是最坚韧的。具抗热强度，弯曲强度，耐疲劳性强度均高，耐磨性和电性能优良。

POM具有很低的摩擦系数和很好的几何稳定性，特别适合于制作齿轮和轴承。由于它还具有耐高温特性，因此还用于管道器件（管道阀门、泵壳体），草坪设备等。

POM（聚甲醛树脂）定义：聚甲醛是一种没有侧链、高密度、高结晶性的线型聚合物。按其分子链中化学结构的不同，可分为均聚甲醛和共聚甲醛两种。两者的重要区别是：均聚甲醛密度、结晶度、熔点都高，但热稳定性差，加工温度范围窄（约10℃），对酸碱稳定性略低；而共聚甲醛密度、结晶度、熔点、强度都较低，但热稳定性好，不易分解，加工温度范围宽（约50℃），对酸碱稳定性较好。是具有优异的综合性能的工程塑料。有良好的物理、机械和化学性能，尤其是有优异的耐摩擦性能。俗称赛钢或夺钢，为第三大通用塑料。适于制作减磨耐磨零件，传动零件，以及化工，仪表等零件。一般性能

聚甲醛是一种表面光滑、有光泽的硬而致密的材料，淡黄或白色，薄壁部分呈半透明。燃烧特性为容易燃烧，离火后继续燃烧，火焰上端呈黄色，下端呈蓝色，发生熔融滴落，有强烈的刺激性甲醛味、鱼腥臭。聚甲醛为白色粉末，一般不透明，着色性好，比重1.41-1.43克/立方厘米，成型收缩率1.2-3.0%，成型温度170-200℃，干燥条件80-90℃2小时。POM的长期耐热性能不高，但短期可达到160℃，其中均聚POM短期耐热比共聚POM高10℃以上，但长期耐热共聚POM反而比均聚POM高10℃左右。可在-40℃～100℃温度范围内长期使用。POM极易分解，分解温度为280度，分解时有刺激性和腐蚀性气体发生。故模具钢材宜选用耐腐蚀性的材料制作。

力学性能

POM强度、刚度高，弹性好，减磨耐磨性好。其力学性能优异，比强度可达50.5MPa，比刚度可达2650MPa，与金属十分接近。POM的力学性能随温度变化小，共聚POM比均聚POM的变化稍大一点。POM的冲击强度较高，但常规冲击不及ABS和PC；POM对缺口敏感，有缺口可使冲击强度下降90%之多。POM的疲劳强度十分突出，10交变载荷作用后，疲劳强度可达35MPa，而PA和PC仅为28MPa。POM的蠕变性与PA相似，在20℃、21MPa、3000h时仅为2.3%，而且受温度的影响很小。POM的摩擦因数小，耐磨性好（POM>PA66>PA6>ABS>HPVC>PS>PC），极限PV值很大，自润滑性好。POM制品对磨时，高载荷作用时易产生类似尖叫的噪声。

电学性能

POM的电绝缘性较好，几乎不受温度和湿度的影响；介电常数和介电损耗在很宽的温度、湿度和频率范围内变化很小；耐电弧性极好，并可在高温下保持。POM的介电强度与厚度有关，厚度0.127mm时为82.7kV/mm，厚度为1.88mm时为23.6kV/mm。

 环境性能

POM不耐强酸和氧化剂，对烯酸及弱酸有一定的稳定性。POM的耐溶剂性良好，可耐烃类、醇类、醛类、醚类、汽油、润滑油及弱碱等，并可在高温下保持相当的化学稳定性。吸水性小，尺寸稳定性好。

POM的耐候性不好，长期在紫外线作用下，力学性能下降，表面发生粉化和龟裂。

成形性

结晶料，熔融范围窄，熔融和凝固快，料温稍低于熔融温度即发生结晶。流动性中等。吸湿小，可不经干燥处理。
