补充资料：超韧性聚甲醛
分子式：
CAS号：
性质：又称超韧性聚甲醛。多采用机械共混法制备。一般需要在高剪切力的双螺杆挤出机或密炼机中进行。它具有如下特性：(1)韧性高，改共混物的缺口冲击强度为聚甲醛(POM)的7倍，无缺口冲击强度为POM的30倍，而且比PC高10倍；(2)吸湿性小，从而保证了制品的尺寸稳定性；(3)耐溶剂性、耐应力开裂性优于PC。以100ST为例，密度1.34g/cm3，拉伸强度46MPa，断裂伸长率200％，弯曲模量1.41GPa，热变形温度(1.86MPa负荷)90℃，悬臂梁缺口冲击强度940J/m。适于制造汽车、农业机械、电器、机械、建筑、运输和精密仪器的零部件等。
