MFI452B
The series melt flow index testers are precision instruments designed to measure the melt flow rate of thermoplastic materials under specified test conditions. The melt flow rate (MFR) or melt volume rate (MVR) represents the mass or volume of molten polymer extruded through a standardized die within 10 minutes at a defined temperature and load. This parameter is critical for assessing polymer processing behavior, ensuring material consistency, and supporting batch quality control across production environments.
Common Applications: Thermoplastics including:
- General-purpose plastics: PE, PP, PS, ABS, PVC, etc.
- Engineering plastics: PA (Nylon), PC, POM, PBT, PET, and others.
