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 determine the Melt Mass Flow Rate (MFR) and Melt Volume Flow Rate (MVR) of thermoplastic resins.It is suitable for engineering plastics with higher melting temperatures, such as polycarbonate, nylon, fluoroplastics, and polysulfone, as well as plastics with lower melting temperatures, including polyethylene, polystyrene, polypropylene, ABS resin, and polyoxymethylene. Designed and manufactured according to national and international standards, this instrument combines the advantages of various domestic and international models. With its simple structure, ease of operation, and convenient maintenance, it is widely used in the plastic raw material, plastic production, plastic products, and petrochemical industries, as well as in colleges, research institutions, and commodity inspection departments.
