Material Characterization
In a logic of continuous analytical and methodological development, the desire to assist and satisfy an increasing number of requests relating to issues associated with different materials and product categories, has led CSI to acquire over time the adequate knowledge to analytically tackle numerous problems. Plastics, rubbers and inorganic materials are characterized from a chemical, physical and mechanical point of view by:
- DSC (Differential Scanning Calorimetry) for the determination of melting points and glass transitions
- FTIR (Fourier Transform InfraRed Spectroscopy) for the qualitative recognition of polymeric matrices;
- TGA (Thermogravimetric Analysis) for the quantification of additives, plasticizers and fillers;
- XRF (X-Ray Fluorescence) for elementary qualitative analysis;
- MFI (Melt Flow Index) for the viscosity properties of the polymers;
- GC and LC combined with specific detectors for quantification of additives and contaminants;
- Tensile strength, COF, resistance to delamination, resistance of welds;
- Permeability to oxygen (ASTM D3985; ASTM F1927); permeability to carbon dioxide (ASTM F2476); permeability to water vapor (ASTM F1249, ASTM E96) and others;
- Resistance to chemicals and substances (stress cracking).
