Film biaxial tensile tester is a common equipment for testing the biaxial tensile properties of polymer sheet films. The film biaxial stretching instrument developed by Guangzhou Putong can make the thickness below 0.2-2mm, and the minimum 70×70mm can be used as a thick film sample of biaxially stretched film material. According to the required stretching ratio, it can be formed at a suitable temperature and time. The film tensile test is used for physical and chemical testing and analysis in the laboratory. According to the properties of the sample film, a wide variety of additives and formulas can be re-determined and applied to the production line, which can greatly reduce the trial production cost.
The rollers with hard chrome plating surface are driven by two independent servo motors. The roll surface temperature is controlled within 5 degrees with the interior heating and water/air cooling system. It is suitable for mixing and dispersing natural rubber and other polymer materials.
Main Test & Control Module is a control console with the function of driving and controlling measurement units. This modular structure has good expandability and adaptability, and can be equipped with various functional modules. Controlled auxiliary machines such as torque and extrusion units are intelligent, application-specific measurement units that transmit measurement data to the host.
