Melt Flow Index Tester

An MFI Tester is used to determine the melt flow behavior of thermoplastic materials. Manufacturers and laboratories use MFI testing to compare material batches, monitor raw material quality, and evaluate thermoplastic materials before or during production. The tester can be used according to standards such as ASTM D1238, IS 2267, IS 2530, and IS 10810, depending on the applicable test method.

A typical MFI test involves placing a specified quantity of thermoplastic material into the heated barrel of the tester. The material is heated to the required test temperature and held for the specified preheating period. A defined load is then applied to the piston. The load forces the molten material through the standard die. The extruded material is collected and measured to determine the melt flow rate in grams per 10 minutes. For example, commonly used test conditions can include 190°C with a 2.16 kg load for certain polyethylene materials and 230°C with a 2.16 kg load for certain polypropylene materials. The exact temperature, load, sample quantity, and test procedure depend on the applicable material specification and testing standard.

The price of a Melt Flow Index Tester in India typically ranges from INR 50,000 to INR 2,00,000, depending on the model, configuration, test loads, features, and accessories.
