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。
