PC材料耐高溫嗎?
耐高溫PC材料的耐熱溫度范圍為-45℃-135℃。超出此溫度范圍,PC材料將變質并失去其固有特性。PC材料,即聚碳酸酯,是一種在分子鏈中包含碳酸酯基團的高分子聚合物。根據酯基的結構,可分為脂族,芳族,脂族-芳族和其他類型。PC是一種幾乎無色的玻璃態無定形聚合物,具有良好的光學性能。PC高分子量樹脂具有很高的韌性,懸臂梁缺口缺口沖擊強度為600?900J/m,未填充級的熱變形溫度約為130°C。玻璃纖維可以將該值增加10°C。PC的彎曲模量可以達到2400MPa以上,并且樹脂可以加工成大的剛性產品。低于100°C,負載下的蠕變速率非常低。PC的耐水解性差,不能用于反復經受高壓蒸汽作用的產品。
