Biaxial hot-drawing of poly(ethylene terephthalate): An experimental study spanning the processing range

Abstract:

An experimental study was made of hot-drawing of PET films under biaxial stress, relevant to industrial orientation processing. The aim was to generate a data set more comprehensive than previously available, to support the development of an improved constitutive model for PET, suitable for process modelling. Isotropic, almost-amorphous films were prepared by extrusion from two grades of PET, with differing molecular weight. The ranges of strain-rate and temperature encompassed were 0.2-16 s-...
