What Does HLMI Stand For?

HLMI stands for High Load Melt Index

HLMI, or High Load Melt Index, is a critical parameter in polymer science that quantifies the flow characteristics of thermoplastic materials under high shear conditions. It measures the viscosity of plastics when subjected to elevated loads, providing insights into their processing behavior and flow properties during manufacturing. A higher HLMI indicates a lower viscosity, facilitating easier processing, while a lower HLMI suggests greater resistance to flow. This metric is essential for selecting appropriate materials for specific applications in industries such as packaging, automotive, and consumer goods.
