GB/T 3682-2000
AbolishedDetermination of the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of thermoplastics
热塑性塑料熔体质量流动速率和熔体体积流动速率的测定
Application Summary AI generated
This standard specifies a method for measuring the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastic materials under specified temperature and load conditions. It is primarily applied in the plastics industry for quality control of raw materials, such as polypropylene or polyethylene, and for evaluating the processability of thermoplastics during injection molding or extrusion. The test results are used to characterize the viscosity and flow behavior of polymer melts, ensuring consistency in manufacturing and material selection.
