硬度增大，而拉伸强度和扯断伸长率则逐渐降低，随老化时间延长，变化趋势逐渐平缓。
The hardness gradually increased, while the tensile strength and elongation at break decreased gradually. With the elongation of time, these change gradually flattened.
2
随着共混物中弹性体质量分数的增加，共混物的拉伸强度和弹性模量降低，扯断伸长率增大。
With the increase of elastomer content, the tensile strength and elastic modulus of the blends decreased, while the elongation at break increased.

The properties of the PVC envelop material modified by CPE was investigated, and the moisture permeability, tensile strength and elongation at break were also tested.

扯断伸长率
橡胶经硫化后，其原有的线型高分子结构被交联成网状结构，分子间作用力增大，具有一定的强度，能承受一定的作用力，将橡胶试样在拉力机上以一定速度拉断时，以试样拉伸前断面积上所承受的力(MPa)来表示拉伸强度。当橡胶试样拉断时，其伸长部分与原长度之比谓之扯断伸长率，以百分率(％)表示。
