Environmental stress cracking tester for geomembrane

Scope of application:

The stress cracking strength of polyolefin geomembrane was measured and evaluated by notch constant load tensile test. During the test, the dumbbell sample with notch prepared in advance is placed in the thermostatic surfactant under constant load tension, and the fracture time of the sample is measured and recorded. A series of test results under different stress levels can establish a relationship between the stress level and the fracture time on the logarithmic axis.
