RHEOLOGY ADDITIVES

  RHEOLOGY

    The most important feature of a thermoplastic is its ability to be processed as a melt that can be shaped by extrusion or moulding. Rheology is the science that deals with the deformation and flow behaviour of objects and melt flow is a concept related to rheology.

    MFI (Melt Flow Index), density and viscosity are important parameters affecting rheology.
