PPO,中文名稱是聚苯醚。是世界五大通用工程塑料之一。它具有高剛性,高耐熱性,阻燃性,高強度和優異的電性能的優點。另外,聚苯醚還具有耐磨性,無毒和耐污染的優點。PPO的介電常數和介電損耗是工程塑料中最小的品種之一。它們幾乎不受溫度和濕度的影響,可用于低,中和高頻電場領域。PPO的載荷變形溫度可達到190°C以上,脆化溫度為-170°C。PPO材料是世界上排名前五的通用工程塑料之一,無毒且相對密度低。(PPO/PA的同類產品僅為1.10-1.13g/cm3。)
機械強度,抗蠕變性,抗應力松弛性,高疲勞強度。PPO/PS合金的耐熱性非常出色。熱變形溫度可以在1.82MPa下從75-170°C連續變化。隨著PPO含量的增加,材料的熱轉變溫度不斷提高。性能要求。PPO及其合金可以采用各種加工方法,例如注塑,擠出,壓塑,發泡和電鍍,真空鍍膜以及印刷機加工。
純PPO材料具有熔體流動性差和價格高的缺點。市場上出售的產品是具有優良綜合性能的改良產品。它們廣泛用于:電子產品:可以滿足濕度要求,高溫條件下優良的電絕緣性。用于制備電視芯片調諧線圈,線圈芯,微波絕緣零件,屏蔽套,高頻印刷電路板,各種高壓電子元件,電視,計算機,傳真機,復印機外殼等。汽車工業:適用用于儀表板零件,窗框,減震器,泵過濾器等機械工業:用作齒輪,軸承,泵葉輪,鼓風機葉輪葉片等。化學領域:用于制造耐腐蝕零件,例如管道,閥門,過濾器和潛水泵。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
