Plastic EVA automatic melt index tester AR-3682MV-AU

The melt flow rate meter refers to the extrusion rate of plastic through a specified length and inner diameter die under certain temperature, load, and piston position conditions. The mass extruded in a specified time is used as the melt mass flow rate, abbreviated as MFR, with the unit of g/10 min; The flow rate of the melt volume, abbreviated as MVR, is measured in cm ³/10 min; The flow rate can distinguish the viscous flow characteristics of thermoplastic in the molten state, help analyze the relative values of material properties, predict the relative difficulty of resin flow during processing, and is a technical indicator in the batching, production, and physical property testing processes.

The AR-3682MV-AU automatic melt index tester for plastic EVA is specially designed for fast and accurate measurement, with features such as sturdy structure, easy operation, stable and reliable performance; High precision PID constant temperature technology is used, with high temperature control accuracy; Nitriding treatment of key components results in high strength and hardness, with minimal thermal expansion deformation; Manually loaded weights with automatic cutting function.

Application of melt index analyzer:

Used to determine the melt mass flow rate (MFR) or melt volume flow rate (MVR) of various plastics and resin polymers in a viscous flow state. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, nylon, etc. with high melting temperatures, as well as for testing plastics with low melting temperatures such as polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), polycarbonate (PC) resin, etc.

Note: Optional test fluorine material available
