Polyethylene characterization by FTIR

Polymer Testing, 2002
Important experimental parameters for FTIR spectra acquisition were studied: apodization, beam aperture, number of scans and spectral resolution, using polyethylene samples. The optimum conditions for the analyses were established and permitted unequivocally to identify the three most important commercially available grades: low density, high density ...

Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

Advanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of
