  POM為白色一般不透明，著色性好， 比重1.41-1.43克/立方厘米，成型收縮率1.2-3.0%，成型溫度170-200℃ ，干燥條件80-90℃ 2小時。POM的長期耐熱性能不高，但短期可達(dá)到160℃，其中均聚POM短期耐熱比共聚POM高10℃以上，但長期耐熱共聚POM反而比均聚POM高10℃左右?？稍?40℃～100℃溫度范圍內(nèi)長期使用。POM極易分解，分解溫度為240度。分解時有刺激性和腐蝕性氣體發(fā)生，故模具鋼材宜選用耐腐蝕性的材料制作。

（1）POM是結(jié)晶型塑料,密度為1.42g/cm3,它的鋼性很好,俗稱“賽鋼”.
　　（2）它具有耐疲勞、耐蠕變、耐磨、耐熱、耐沖擊等優(yōu)良的性能,且摩擦系數(shù)小,自潤滑性好.
　?。?）POM不易吸濕,吸水率為0.22～0.25%,在潮濕的環(huán)境中尺寸穩(wěn)定性好,其收縮率為2.1%(較大),注塑時尺寸較難控制,熱變形溫度為172℃
 
   POM強(qiáng)度、剛度高，彈性好，減磨耐磨性好。其力學(xué)性能優(yōu)異，比強(qiáng)度可達(dá)50.5MPa，比剛度可達(dá)2650MPa，與金屬十分接近。POM的力學(xué)性能隨溫度變化小，共聚POM比均聚POM的變化稍大一點(diǎn)。POM的沖擊強(qiáng)度較高，但常規(guī)沖擊不及ABS和PC；POM對缺口敏感，有缺口可使沖擊強(qiáng)度下降90%之多。POM的疲勞強(qiáng)度十分突出，10交變載荷作用后，疲勞強(qiáng)度可達(dá)35MPa，而PA和PC僅為28MPa。POM的蠕變性與PA相似，在20℃、21MPa、3000h時僅為2.3%，而且受溫度的影響很小。POM的摩擦因數(shù)小，耐磨性好（POM>PA66>PA6>ABS>HPVC>PS>PC），極限PV值很大，自潤滑性好。POM制品對磨時，高載荷作用時易產(chǎn)生類似尖叫的噪聲。

   POM的電絕緣性較好，幾乎不受溫度和濕度的影響；介電常數(shù)和介電損耗在很寬的溫度、濕度和頻率范圍內(nèi)變化很?。荒碗娀⌒詷O好，并可在高溫下保持。POM的介電強(qiáng)度與厚度有關(guān)，厚度0.127mm時為82.7kV/mm，厚度為1.88mm時為23.6kV/mm。
環(huán)境性能

POM不耐強(qiáng)堿和氧化劑，對烯酸及弱酸有一定的穩(wěn)定性。POM的耐溶劑性良好，可耐烴類、醇類、醛類、醚類、汽油、潤滑油及弱堿等，并可在高溫下保持相當(dāng)?shù)幕瘜W(xué)穩(wěn)定性。吸水性小，尺寸穩(wěn)定性好。
POM的耐候性不好，長期在紫外線作用下，力學(xué)性能下降，表面發(fā)生粉化和龜裂。

⒈增強(qiáng)POM
主要增強(qiáng)材料為玻璃纖維、玻璃球或碳纖維等，并且玻璃纖維常用，增強(qiáng)后的力學(xué)性能可提高2～3倍，熱變形溫度提高50℃以上。
⒉高潤滑POM
在POM中加入石墨、F4、二硫化鉬、潤滑油及低分子量PE等，可提高其潤滑性能。例如，在POM中加入5份F4，可降低摩擦因數(shù)60%，耐磨性提高1～2倍。再如，在POM中加入液體潤滑油，可大幅度提高耐磨性和極限PV值

POM又稱賽鋼、特鋼。它是聚合所得。POM-H，POM-K是高密度、高結(jié)晶度的熱塑性工程塑料。具有良好的物理、機(jī)械和化學(xué)性能，尤其是有優(yōu)異的耐摩擦性能。

POM是一種表面光滑，有光澤的硬而致密的材料，淡黃或白色，可在-40- 100°C溫度范圍內(nèi)長期使用。它的耐磨性和自潤滑性也比絕大多數(shù)工程塑料優(yōu)越，又有良好的耐油，耐過氧化物性能。很不耐酸，不耐強(qiáng)堿和不耐紫外線的輻射。(加入U(xiǎn)V劑，能大大提高其耐紫外線等級）
