It is used to determine the MFR value of the melt flow rate of various plastics and resins in a viscous flow state. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, nylon, etc., with higher melting temperature, also for polyethylene (PE) , Polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), polycarbonate (PC) resin and other low melting temperature plastic testing, widely used in plastic production, plastic products, petroleum Chemical and other industries, as well as related colleges, research institutes and commodity inspection departments.
