分子式：
CAS号：
性质：拉伸时试样长度的增加。通常用试样原始长度的百分率表示。所以亦有称伸长百分离（percentage of elongation）。ε=[(L-L0)/L0]×100%。式中：ε为伸长率，%；L0为试样的原始长度，m；L为试样变形后的长度，m。伸长率是材料的基本力学量，表征了材料在外力作用下的延伸性和韧性。高聚物的这一性能和温度、加载速度等因素有很大关系。（一）皮革试样在10N负荷作用下，被拉伸试验机拉断时的总伸长率与原长度的比值，以百分率表示。能在一定程度上反是非曲直皮革纤维组织的弹性变形的物理性能。许多种皮革按用途不同被规定出不同的伸长率，如铬鞣黄牛皮正鞋面革的伸长率（在抗张强度为10N/mm2时）应为20%～35%。（二）纸或纸板在受到和试样平行的张力而发生断裂时的伸长，以对试样原有长度的百分比表示。纸为弹塑体，它和受环境影响而产生的伸缩率是有区别的。伸长率一般多和抗张强度同时测定。重施胶纸的伸长率低于1%，而皱文纸的伸长率可达250%，长网造纸机的所抄纸张的横向伸长率约为纵向伸长率的两倍左右。
