XRL—400B series melt flow rate meter is an instrument used to characterize the flow performance of thermoplastic polymers in a viscous flow state. It is used to determine the melt mass flow rate (MFR) and melt volume flow rate (MVR) of thermoplastic resins. , Melt flow rate meter is not only suitable for engineering plastics such as polycarbonate, nylon, fluoroplastics, polyarylsulfone, etc., with higher melting temperature, but also suitable for polyethylene, polystyrene, polypropylene, ABS resin, polyoxymethylene resin, etc. Plastic testing with lower melting temperature is widely used in plastic raw materials, plastic production, plastic products, petrochemical industries and related universities, research institutes, and commodity inspection departments.
