POM材料簡介。POM是一種硬而致密的材料，表面光滑，有光澤，通常是淺黃色或白色，薄壁部分是半透明的。燃燒特性易于燃燒，并且在離開火源后繼續(xù)燃燒，火焰的上端是黃色，下端是藍色，它融化并滴落，并具有強烈的刺激性氣味。POM具有良好的物理，機械和化學性能，尤其是優(yōu)異的耐摩擦性，在寬廣的溫度和濕度范圍內(nèi)具有良好的自潤滑性，良好的抗疲勞性和彈性。另外它具有良好的耐化學性。如果聚合度不高，容易受熱解聚。pom材料粒子通過熱注塑工藝高溫擠出可以制成不同厚度的pom板就或者不同直徑尺寸的pom棒。 pom有良好的耐溶劑、耐油類、耐弱酸弱堿等性能。有很高的硬度鋼性，具有高度抗蠕變應力松馳能力，自潤滑性.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="常州黑色pom板供應商家,pom"

怎樣區(qū)分POM板棒是均聚還是共聚？POM棒/板一般有以下幾種型號：POM-C/H（黑色、白色）：分別表示POM共聚物和POM均聚物，POM共聚物熔點低、熱穩(wěn)定性、耐化學腐蝕性、流動特性、耐水解、耐強堿和熱力氧化降級、加工性優(yōu)于均聚甲醛。POM均聚物結(jié)晶度高、搞蠕變性、熱膨脹率更低、耐磨性、機械強度、剛性、熱變形溫度等比共聚甲醛好。（目前市面上POM半成品普遍使用POM-C共聚物）POM-H+PTFE（深棕色）：POM+TF棒/板是用杜邦POM（DELRIN）原料加PTFE（鐵氟龍）纖維擠出而成。它保留了POM-H的大多數(shù)固有強度。因填加PTFE（鐵氟龍）纖維而有某些性能改變，稍軟，剛性小，比純的聚甲醛樹脂更滑。與純POM板比較，該材料潤滑更好。用POM-H+PTFE制造的軸承摩擦系數(shù)中等，耐磨，并且基本無蠕動現(xiàn)象。由于均聚物里共聚成分的插入,除了熱穩(wěn)定性外,其它性質(zhì)也發(fā)生了一些變化.一般,共聚成分是多一個碳元素的氧化乙烯基-CH2CH2O-.雖然因引入的比例而異,但是可以說,共聚甲醛的性質(zhì)是在甲醛均聚物中加入氧化乙烯聚合物而共同形成的.下面,對甲醛共聚物與均聚物標準品級的物性進行一下比較.雖然在短期機械特性方面,有均聚物高于共聚物的傾向,但在長期機械特性方面，共聚物則比均聚物降低的比例小。常州黑色pom板供應商家</p><p
