Role of Rheology in Melt Processing

  • Chapter
  • First Online:
Melt Rheology and its Applications in the Plastics Industry

Part of the book series: Engineering Materials and Processes ((EMP))

Abstract

Rheological properties govern the behavior of polymers in melt forming operations. This chapter first explores melt behavior in channels, dies and extruders where the viscometric functions play a dominant role. Extrudate swell, wall slip, flow instabilities, and die build-up are described. The remaining operations dealt with are those in which elasticity is important. Processes for making sheet and film are described and processing problems related to rheology are explained. The roles of rheology in blow molding, injection molding, rotational molding and foam formation are taken up in the remainder of the chapter.
