Definition of a noun: The definition of melt index is: .
The melt index is the weight of the melt of a thermoplastic that passes through a standard capillary within ten minutes under certain temperature and pressure, expressed in (g/10min).
Melt index is a value that indicates the flowability of plastic materials during processing. It was developed by the American Society for Testing and Materials (ASTM) based on the methods used by DuPont in the United States to evaluate plastic properties. The testing procedure involves melting plastic pellets into a plastic fluid over a certain period of time (10 minutes), at specific temperatures and pressures (which vary depending on the material), and then measuring the amount of grams that flow through a tube with a diameter of 2.1 mm. The higher this value, the better the processability of the plastic material; conversely, the lower it is, the worse the processability.
Melt index: It is the weight of the melt of a thermoplastic resin that passes through a standard capillary within ten minutes under certain temperature and pressure, expressed in (g/10min). High melt index, good flowability ； The melt index is low, resulting in poor flowability.
Melt index is a value that indicates the flowability of plastic materials during processing
It refers to the mass of polymer that passes through a certain pore per unit time under specific conditions (temperature, pressure). The unit is g/10min.
It represents a value indicating the fluidity of plastic materials during processing. It is generally expressed as the weight of the melt passing through a standard capillary within 10 minutes, using thermoplastic materials under certain temperature and pressure conditions; the unit is g/10min.

Melt index is a value that indicates the flowability of plastic materials during processing. It was developed by the American Society for Testing and Materials (ASTM) based on the methods used by DuPont in the United States to evaluate plastic properties. The testing procedure involves melting plastic pellets into a plastic fluid over a certain period of time (10 minutes) at specific temperatures and pressures (which vary depending on the material), and then measuring the amount of weight in grams that flows through a tube with a diameter of 2.095 mm. The higher this value, the better the processability of the plastic material; conversely, the lower it is, the worse the processability.
