The melt flow index (MFI) is a crucial parameter in the plastics industry that measures the ease of flow of a thermoplastic polymer when melted. Expressed in grams per 10 minutes, MFI indicates how much polymer can pass through a specific die under standard temperature and pressure. This property helps manufacturers assess the processability of plastic materials during molding or extrusion. A higher melt flow index suggests lower viscosity, suitable for injection molding, while a lower MFI is preferred for extrusion processes. Understanding the melt flow index ensures material consistency, quality control, and efficient production—making it an essential factor in selecting the right polymer for various industrial applications.
