  "id": "MLC-T-CHM-007150",
  "term": "Melt flow index",
  "field": "Chemistry",
  "definition": "A measure of the thermoplastic polymer's ability to flow under specific conditions of temperature and pressure, indicating its processability. It quantifies the mass of polymer extruded through a die of standard dimensions in a given time. This value is inversely related to the polymer's molecular weight and is typically expressed in grams per 10 minutes (g/10 min).",
