Scope of Application

【Operating Instructions】

The Melt Flow Rate Tester is an instrument used to characterize the flow properties of thermoplastic polymers in a viscous flow state. It is designed to measure the Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR) of thermoplastic resins.It is suitable for engineering plastics with high melting temperatures, such as Polycarbonate (PC), Nylon, Fluoroplastics, and Polysulfone, as well as plastics with lower melting temperatures like Polyethylene (PE), Polystyrene (PS), Polypropylene (PP), ABS resin, and Polyoxymethylene (POM).
