Examples of 'melt index' in a sentence
Meaning of "melt index"
Melt index is a measurement used to determine the flow properties or melt flow rate of a thermoplastic material, particularly plastics. It quantifies the ability of a molten plastic to flow under specific temperature and pressure conditions. The melt index is often used as an indicator of the material's viscosity, processability, or characteristics related to its composition, structure, and molecular weight
