Product details
Product Introduction
Polymer creep testing machine is a device that evaluates the creep characteristics of materials at high temperatures, using added weights to directly load the sample. Compared with mechanical testing machines, the accuracy of load loading is high, but the limitation of load loading is its disadvantage. There are two types of testing machines that perform constant load loading on the sample at high temperatures and measure the fracture time of the sample, and use the same method to detect the deformation of the sample in real time.
