One of the most essential tools used to evaluate plastic materials is the Melt Flow Index Tester (also known as MFI Tester). This instrument helps determine how a polymer behaves when melted, which directly impacts processing, molding, and end-use performance.
At Pacorr Testing Instruments, we provide advanced and reliable Melt Flow Index Testers designed to meet global testing standards and support the highest levels of quality assurance.
What is a Melt Flow Index Tester?
A Melt Flow Index Tester measures the rate at which a thermoplastic polymer flows when subjected to specific temperature and load conditions. The test results are expressed in grams per 10 minutes — indicating how much polymer extrudes through a standard die over that time period.
This testing method is defined by ASTM D1238 and ISO 1133, making it a standard practice across industries that rely on thermoplastic materials. The MFI value helps manufacturers understand the melt viscosity of the material, which is essential for processes like injection molding, extrusion, and blow molding.
Why is MFI Testing Essential?
The Melt Flow Index isn’t just a number—it represents how a material will behave during manufacturing. Here are a few reasons why MFI testing is critical:
Ensures Product Consistency: Helps maintain uniform quality across different production batches.
Supports Material Selection: Allows engineers to select polymers with the right flow properties for their intended application.
Improves Processing Efficiency: Helps determine optimal molding and extrusion conditions.
Detects Degradation: Identifies changes in polymer behavior due to thermal or mechanical stress.
Complies with Industry Standards: Many regulations and product specifications require melt flow testing documentation.
