聚甲醛(英文：polyformaldehyde)別名縮醛樹脂（acetalnresins）；聚氧亞甲基（polyoxymethylenes）。全名聚甲醛樹脂，簡稱聚甲醛，熱塑性結晶聚合物。被譽為“超鋼”或者“賽鋼”。經過甲醛聚合所得之聚合物，聚合度不高，且易受熱解聚。聚甲醛（POM）是一種機能優良的工程塑料，在國際有“奪鋼”、“超鋼”之稱。POM具有近似金屬的硬度、強度和鋼性，在很寬的溫度和濕度范圍內都具有很好的自光滑性、優越的耐疲勞性，并富于彈性，另外它還有較好的耐化學品性。POM以低于其他很多工程塑料的成本，正在替代一些傳統上被金屬所占領的市場，如替代鋅、黃銅、鋁和鋼制作很多部件，自問世以來，POM曾經遍及使用于電子電氣、機械、儀表、日用輕工、汽車、建材、農業等領域。在良多新領域的使用，如醫療技能、運動器械等方面，POM也顯示出較好的增長態勢。遍及用于制造各種滑動、轉動機械零件，做各種齒輪、杠桿、滑輪、鏈輪，特地適宜做軸承，熱水閥門、精密計量閥、輸送機的鏈環和輥子、流量計、汽車表里部把手、曲柄等車窗轉動機械，油泵軸承座和葉輪燃氣開關閥、電子開關零件、緊固體、接線柱鏡面罩、電電扇零件、加熱板、儀表鈕；錄音錄像帶的軸承；各種管道和農業噴灌系統以及閥門、噴頭、水龍頭、沐浴盆零件；開關鍵盤、按鈕、音像帶卷軸；溫控準時器；動力東西，庭園收拾整頓東西零件；別的可作為沖浪板、風帆及各種雪撬零件，手表微型齒輪、體育用裝備的框架輔件和背包用各種環扣、緊固件、打火機、拉鏈、扣環；醫療器械中的心臟起博器；人造心臟瓣膜、頂椎、假肢等用于化工、制藥等化學合成及運用無水甲醛作原料的合成方面。 。以上文獻若需轉載請備注出處：pbt塑料 //shanglikaiguan.cn/
