The biaxial tensile test can be conducted on any crystalline and amorphous polymer (PET, PETG.PA, PP, PE, PS, EVA, etc.) thick sheets with a thickness of less than 1.2mm and 120mm square that can be used for biaxial stretching. (1) It can realize bidirectional synchronous or asynchronous stretching;
(2) The stretching ratio in the vertical and horizontal directions is adjustable, and the maximum stretching is 8X8, that is, the maximum stretching in the vertical and horizontal directions is 8 times;
(3) The longitudinal and transverse stretching speed is adjustable, and the maximum stretching speed is 0.35m/s;
(4) In the tensile zone, the maximum temperature is 2401.5 ℃.
