100°C溫度范圍內(nèi)長(zhǎng)期使用。它的耐磨性和自潤(rùn)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(guò)氧化物性能。很不耐酸，不耐強(qiáng)堿和不耐月光紫外線的輻射。聚甲醛的拉伸強(qiáng)度達(dá)70MPa，吸水性小，尺寸穩(wěn)定，有光澤，這些性能都比尼龍好，聚甲醛為高度結(jié)晶的樹(shù)脂，在熱塑性樹(shù)脂中是zui堅(jiān)韌的。具抗熱強(qiáng)度，彎曲強(qiáng)度，耐疲勞性強(qiáng)度均高，耐磨性和電性能優(yōu)良。提高聚甲醛的耐候性：在聚甲醛中加入抗氧劑及光穩(wěn)定劑可以提高聚甲醛的耐候性。針對(duì)POM受紫外線照射易發(fā)生白化，日本三菱POMFS2022、龜裂等缺點(diǎn)，一些科研機(jī)構(gòu)紛紛開(kāi)發(fā)出耐候型品種，以滿足汽車內(nèi)外裝飾材料的要求。導(dǎo)電、抗靜電聚甲醛：采用加入炭黑、碳纖維、不銹鋼纖維等導(dǎo)電填充料的方法，可以提高聚甲醛導(dǎo)電性能。在聚甲醛中加入特殊的抗靜電劑則可使聚甲醛具有抗靜電性，減少其在電子領(lǐng)域應(yīng)用時(shí)因灰塵、碎屑積聚及靜電荷產(chǎn)生的干擾。聚甲醛比強(qiáng)度和比剛性接近于金屬；拉伸強(qiáng)度，日本三菱POMFS2022，彎曲強(qiáng)度，耐蠕變性和耐疲勞性優(yōu)異。日本三菱POMFS2022</p><div

3.替代聚四氟乙烯：摩擦磨耗特性與耐疲勞、耐蠕變性，使得其在許多應(yīng)用中能夠取代聚四氟乙烯。聚甲醛之所以有前景極好以及能扮演多面角色這兩個(gè)好處，就是它有過(guò)千頭萬(wàn)緒的不同用法，有了太多的商業(yè)上可以得到的現(xiàn)成的品級(jí)選擇范圍，色的摩擦磨耗特性加上出色的剛性抗蠕變及抵御烴類的能力，市場(chǎng)上的地位可用強(qiáng)勁二字來(lái)描述。日本三菱POMFS2022</p><p
