PMMA 45抵抗®挤压丙烯酸 高分级冲击强度

PMMA 45抵抗®挤压丙烯酸

类别：聚合物；热塑性塑料；丙烯酸（有机玻璃）；丙烯酸，挤出级。

材料说明：有机玻璃®XT挤压丙烯酸具有以下特性：绝对无色透明，打破耐冲击抗（有机玻璃抗®），无与伦比的抗风化和老化，非常好的表面；辉煌，纹理或缎（德固赛磨砂板®），板材，管，圆棒，多皮片，波纹片，反射镜，1.5至25毫米厚的板材，多皮片16毫米和32毫米厚，标准尺寸为4050×2050毫米（+额外长度），25多个标准色，耐稀酸，有机溶剂的限制性，良好的抗碱，易于工作，类似于硬木，容易成型的最佳常数条件下，易粘结也与溶剂粘合剂（如acrifix®116，117），烧得越来越少，像硬木，很少有烟的产生最高使用温度约70°C

该材料的具体说明：高、分级冲击强度、降低刚度、紫外吸收的标准牌号。
