PRINCIPLE OF THE MFI TESTS The melt flow index measurement is performed by means of a Melt Flow Tester, which operates with a constant pressure, exerted by a constant force due to a known weight on a capillary tube whose area remains constant. The ASTM-D1238 standard is commonly used to perform this operation. The melt flow index (MFI) is a measure of the flow capacity of the resin under controlled conditions and can be easily measured with an equipment called a plastometer, using very low deformation rates, a temperature and a dead weight applied on the piston according to the Standards ASTM D 1238, ISO 1133 ...

This variable is inversely related to viscosity and molecular weight (MW), that is, as the resin's fluid index increases, a decrease in viscosity and molecular weight. For Manual test (Method A - Gravimetric)

• Kit includes all standard work-cleaning tools, piston and nozzle.

• Standard temperature range up to + 325ºC (*) with resolution of ±0.1ºC

• Digital Stopwatch: with a range of up to 9999 seconds • Automatic sample cutting

• 7 chrome and polished weights included in the standard supply: 1.2 Kg - 2.16 Kg - 3.8 Kg - 5 Kg - 5 Kg - 6.6 and 10 Kg
