Multiaxial Elongational Behaviour of Radiation Cross Linked Polyamide Melts
The elongational deformation behaviour of polymer melts is of significant importance for processing technologies such as thermoforming, blow moulding or film stretching. The rheological properties in elongation depend on the molecular structure of the polymer and on the complex boundary conditions of the processes. Especially cross linking of the macromolecules leads to strain hardening and robust material properties which are beneficial for processing. In this article the influence of cross linking on the elongational behaviour of polyamide 12 melts in uniaxial, planar and equibiaxial elongation are investigated. For multiaxial characterization a new measurement setup, combining a stretching frame with an optical deformation measurement system, is utilized.
