FTIR analysis of LDPE and XLPE thin samples pressed between different protective anti-adhesive films

Roman Kochetov, Thomas Christen, Francesco Gullo

Abstract

We investigate the influence of the type of anti-adhesive films used in the production of polyethylene thin samples on their final chemical composition. For this purpose, LDPE and XLPE films were produced by compression molding at different temperatures and using two different polyethylene terephthalate (PET, Mylar) protective sheets, polyimide (Kapton) film and aluminum (Al) foil. These films were then investigated with Fourier Transform Infrared (FTIR) analysis. The influence of peroxide concentration in XLPE granules and of the production temperature protocol on the FTIR spectra of LDPE films were studied as well. From the results we conclude that the effects of the protective films should be considered when producing polymer samples for DC conduction experiments.
