__%%( color: #003399; font-size: 16px;)MFI:__ This value gives an indication of the fluidity of the molten polymer. The MFI is an important value for prediction of processing behaviour. For this reason, the MFI is one of the main properties used in selection of materials. The MFI could be seen as a measured viscosity at a single temperature and shear rate. The MFI of a material is often measured at a specified temperature and weight. However, due to the fact that the viscosity of polymers is shear-dependent, the MFI could also be measured at multiple weights (shear rates).

__%%( color: #003399; font-size: 16px;)Impact strength:__ The energy needed for brittle fracture of a material. The greater the value, the more resistant the material is to breaking upon impact. Impact strength can be measured via Charpy or Izod methods. Samples could be measured notched or unnotched. Notched values are lower than unnotched values due to the limitation of energy dissipation throughout the sample. Furthermore, the impact strength can be measured at different temperatures to predict impact behavior in different environments.
