style="text-indent:25px">聚碳酸酯的性能1、阻燃性能。2010年11月上海市膠州路一場(chǎng)大火，讓防火阻燃材料備受人們的關(guān)注。相較于其他塑料而言，聚碳酸酯有著優(yōu)異的防火性能。在不添加任何阻燃劑的情況下，純的聚碳酸酯就可以通過(guò)一定級(jí)別的防火測(cè)試。如果輔以少量的阻燃劑，聚碳酸酯就能達(dá)到較高級(jí)別的防火標(biāo)準(zhǔn)，同時(shí)，還不會(huì)損失其優(yōu)良的光學(xué)以及力學(xué)性能，這是其他塑料產(chǎn)品根本做不到的。2、耐高溫性。隨著溫度的升高，所有塑料都會(huì)在一定溫度下變軟，從而失去使用價(jià)值。這個(gè)溫度值也就是該塑料的較高使用溫度?？梢韵胂?，這個(gè)溫度數(shù)值越高，塑料的使用范圍也就越寬。聚碳酸酯的較高使用溫度可以達(dá)到120度至130度。大約十幾年前，流行過(guò)所謂的“太空杯”，透明、輕便，它就是以聚碳酸酯為原材料制作的。除了以上所說(shuō)的特性，聚碳酸酯還有其他一些優(yōu)良性能，比如電學(xué)性能、尺寸穩(wěn)定性等等，這里不再贅述。</p><p
