This machine is used for testing the low-temperature resistance performance of rubber. It uses a compressor to provide a constant low-temperature environment and can heat up according to the set heating rate. The cooling medium is alcohol (provided by the customer), which is used to evaluate the low-temperature resistance of rubber through the machine's dedicated torsional power system, torsional angle measurement system, temperature control system, and programmable software calculation system. The torsional stiffness, torsional modulus, and corresponding temperature of rubber are measured at low temperatures.
