style="font-family:"font-size:14px;">Pom棒深受大眾喜愛，這與它的一些特性是分不開的。pom棒有很多的特性，首先就其物理特性，pom棒是一種表面光滑的，并且光澤的一種致密的材料，吸水率相對來說比較的低，并且結(jié)晶度高，尺寸固定。而它的機(jī)械性能來說，這種材料具有比較高的硬度和剛性，還有松弛能力，耐磨性和潤滑性比較的好。它的熱性能主要特點(diǎn)是有著比較較高的熱變性溫度，可在很高的溫度下進(jìn)行使用，這是大多數(shù)其他材料不能與之相比的。另外它的電性能的特征是它的介質(zhì)損耗較低，同時(shí)還能保持較好的耐弧性。它的化學(xué)性能是具有良好的耐溶性、耐油性、耐弱酸性和耐弱堿性。</span>
