1. Introduction:
A Melt Flow Index Tester is a crucial instrument used in the plastic and polymer industry to measure the flow properties of molten thermoplastic materials. It provides a standard value known as the melt flow rate (MFR), which helps manufacturers assess the viscosity and quality of raw plastic resins.
2. Function & Importance:
The tester works by extruding molten plastic through a die under specific temperature and pressure conditions. The amount of material that flows in ten minutes is measured. A higher MFI indicates lower visibility, and vice versa. This data is essential in ensuring material consistency, process control, and product quality.
3. Applications:
MFI testers are widely used in quality control labs, R&D centers, and plastic manufacturing plants. They assist in comparing material grades, selecting suitable raw materials for different applications, and maintaining compliance with global standards like ASTM D1238 and ISO 1133.
