Density - Helium/Argon Pycnometry, allowing accurate recording of very small variations in density to a few tens of 1 mg/cm3.
Rheological Behavior: by MFI.
Chemical Analysis/Reverse Engineering: gas chromatography, GC/MS, HPLC/MS, atomic absorption spectroscopy, element analysis, FTIR, ion chromatography, etc.
Oven Aging: at temperatures up to 300°C with recordable temperature history.
UV Stability: by outdoor weathering or UV (Xenon) exposure + color measurement (ΔE, WI, YI).
Thermal Analysis (DSC and TGA)
Adhesion: wetting angle measurement
GPC (gel permeation chromatography) for the investigation of molecular weight distribution.
