Melt Flow Index.
A Melt Flow Indexer (MFI) is used to measure the melt flow rate of thermoplastic polymers. The Melt Flow Index (MFI) value indicates how easily a polymer flows in molten condition under specified temperature and load conditions.
MFI testing helps to:
-
Differentiate polymer grades
-
Evaluate processing characteristics
-
Assess effects of additives on flowability and stability
-
Support quality control and material selection
Applicable Standards
-
ASTM D1238 – Method A & B
-
ISO 1133
-
IS 2508 / IS 2530
-
BS and other equivalent international standards
