Melt Flow Index (MFI, MFR, MVR) Testing Equipment (also known as melt index instrument) is a special instrument for measuring the melt flow rate of thermoplastics under certain conditions.The melt flow rate (melt index) of thermoplastics refers to the mass or melting volume of the melt passing through the standard die capillary every 10 minutes at a certain temperature and load. It is expressed by MFR (MI) or MVR value, which can distinguish the viscous flow characteristics of thermoplastics in the molten state.It is of great significance to the quality assurance of raw materials and products of thermoplastics and chemical fiber.
