Melt flow rate meter is used to determine the melt mass flow rate (MFR), melt volume flow rate (MVR) and melt density of thermoplastic resins. It is not only suitable for polycarbonate with higher melting temperature, Nylon, fluoroplastics, polyarylsulfone and other engineering plastics are also suitable for testing plastics with lower melting temperature such as polyethylene, polystyrene, polypropylene, ABS resin, polyoxymethylene resin, etc, widely used in plastic raw materials, products, petrochemical and other industries, as well as related colleges and universities, scientific research institutions and commodity inspection departments.
