Title: Material characterization and thermoforming of polyethylene terephthalate film for electrical insulation: Topical report

Technical Report ·
OSTI ID:5732784

Differential scanning calorimetry (DSC) was used to determine as-received glass transition, crystallization, and melting temperatures of polyethylene terephthalate (PET). A Box-Behnken statistical designed experiment was used to evaluate the effect of forming temperature, forming rate, and heat-set temperature on shrinkage, tear resistance, and thermal properties. At a forming temperature of 88/sup 0/C and heat-set temperature of 180/sup 0/C, good-quality PET parts were produced. The optimum forming time appears to be either 0.5 min or 5.0 min. In addition, inductively coupled argon plasma emission spectroscopy (ICAP) was used to determine the catalyst system for both PET sheets from two vendors.
