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 filtration pressure value tester consists of precision screw extrusion system and special melt pump. The melt pressure sensor is installed in front of the pump and a pressure-screw-speed control loop is formed. Screen changer can be disassembled and assembled easily and quickly for easy replacement of the screen, the perforated plate support multi-layer screen. The test curves and reports of FPV filtration pressure value can be generated by testing and recording the pressure changes during polymer extrusion with melt pressure sensor through dedicated software.
