t is used to measure the MFR value of melt flow rate of various plastics and resins in viscous flow state. It is not only applicable to engineering plastics such as polycarbonate, polysulfone, fluoroplastics and nylon with high melting temperature, but also applicable to the testing of plastics with low melting temperature such as polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, POM and polycarbonate (PC) resin. It is widely used in plastic production, plastic products Petrochemical and other industries, as well as relevant colleges and universities, scientific research institutions and commodity inspection departments.
