PC塑料管和PVC首先在材料上有所不同,因此在應用,性能和價格上存在許多差異。PC(聚碳酸酯)樹脂是一種優異的工程熱塑性塑料,具有出色的抗沖擊性,良好的抗蠕變性和尺寸穩定性,耐熱性,低吸水率,無毒和優異的介電性能。工程塑料中唯一具有良好透明度的產品也是近年來增長最快的普通工程塑料。PVC樹脂塑料產品的突出優點是阻燃性,耐磨性,耐化學性以及氣體和水蒸氣的低泄漏。此外,綜合機械性能,產品透明度,電絕緣性,隔熱性,隔音性和減震性也都很好。它是具有最佳性能價格比的通用材料。缺點是熱穩定性和抗沖擊性差,并且無論是硬質PVC還是軟質PVC在使用過程中都容易變脆。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
