  • MFI-100 is designed specifically for use in the Quality Control Department as a quick and easy Melt Flow Indexer for thermoplastic materials according to the “A” Method of the international standards of MFI, ASTM D1238 – ISO 1133 in both Procedure A (Gravimetric).

    • GRAVIMETRIC method
    • Low cost
    • Automatic Sample Cutting
    • Robust design with high rigidity
    • PID temperature controller (maintain +/- 0.1 ° C)
    • Time programmer and number of cutting cycles
    • Equipment ready to work with corrosive materials such as PVC
  • Principles

    The melt index measurement is performed by a meter Flow Index, which operates with a constant pressure exerted by a constant force due to a known weight into a capillary tube whose area remains constant. ASTM-D1238 is commonly used to perform this operation

    The melt flow index (MFI) is a measure of the flowability of the resin under controlled conditions and can be easily measured with equipment called plastometer, using very low strain rates, a temperature of 230 ° C and weighing 2.16 kg according to ASTM D 1238 & ISO 1133. This variable is inversely related to the viscosity and molecular weight (MW), that is, with increasing the melt index of the resin, a decrease is obtained in viscosity and molecular weight.
