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，因為可以減輕質量的同時不會降低強度，需要材料具有很好的剛性。現在國內已經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。</p><p> <span style="font-family:"font-size:14px;"> 在pom實際運用上面，通常都會聽到一個名詞叫玻纖增強pom?其實，所謂的玻纖增強pom，就是當客戶對材料的沖擊強度和剛性有相對較高的要求時，就要考慮推薦增強填充級牌號，通過玻璃纖維進行增強改性，來提高pom材料的機械性能。增強過后的POM聚甲醛因其機械性能得到較大的提高，所以在機械零部件、汽車工業(yè)等行業(yè)應用大量的。并且增強后的pom產品是一種**高,高剛性材料,適宜于替代一些鋅,鋁或銅合金零件,是制作結構件的理想材料.該材料用于注射轎車部件,如搖窗機導板,卷繩筒等.在電子電器行業(yè)中作錄音機,錄像機機芯結構件,制作高壓開關活門.潤滑劑改性增強POM</span><span
