Gehman Torsion Tester




The test machine is used to determine the relative stiffness properties of hardened or thermoplastic rubber, also known as the Gehman test. The movement of the rubber molecules becomes inactive from room temperature to low temperature, and it will be frozen and can not achieve the original function under the glass transition temperature (Tg). The Gehman test can also be used to determine the elastic recovery characteristics of rubber.
