style="font-size:14px;font-family:"">其中，聚甲醛（POM）是一種性能優(yōu)良的工程塑料，在國外有“賽鋼”、“奪鋼”、“超鋼”之稱。POM具有類似金屬的硬度、強度和鋼性，在很寬的溫度和濕度范圍內(nèi)都具有很好的自潤滑性、良好的耐疲勞性，并富于彈性，此外它還有較好的耐化學品性。POM以低于其他許多工程塑料的成本，正在替代一些傳統(tǒng)上被金屬所占領的市場，如替代鋅、黃銅、鋁和鋼制作許多部件，自問世以來，POM已經(jīng)廣泛應用于電子電氣、機械、儀表、日用輕工、汽車、建材、農(nóng)業(yè)等領域。</span><span style="font-size:14px;font-family:"">它不僅可減輕零部件約40%的重量，而且還可以使采購成本降低20%-30%左右，因此近年來在汽車中的用量迅速上升。而共聚甲醛（POM）由于其出色的剛度、耐磨性、抗腐蝕性、降低成本等特性成為了汽車制造商的“新寵”。將來，POM材料還將進一步改良，逐漸替代鋁、鋼、銅等材料在汽車中的應用，在汽車輕量化和降本方面作出更大的貢獻。</span>

pom材料制成的板材成型品在我們生活中非常常見，舉個列子---汽車保險杠支架，保險杠大家應該都知道，用于汽車碰撞保護，那么保險杠支架是什么呢？主要是為了起到固定支撐保險杠的作用嗎，目前不少汽車的保險杠支架選擇的是塑料材質(zhì)，因為可以減輕質(zhì)量的同時不會降低強度，需要材料具有很好的剛性。現(xiàn)在國內(nèi)已經(jīng)有很多商家開始注意到汽車保險杠用pom材料了，因為保險杠選材中要注意幾點要求，1-良好的尺寸穩(wěn)定性，2-高機械強度，3-高沖擊強度，不易斷裂，4-良好的耐腐蝕性，5-可注塑性，由于保險杠支架需要有很好的機械強度和高抗沖擊特點，而pom料剛好可以滿足這些特性，因此拿來做保險杠未嘗不可。常州防靜電pom板哪里有賣</p><p
