ANALYSIS OF RUBBERS, PLASTICS, AND SYNTHETIC FIBERS IN TURIN
The analysis of polymeric materials requires the use of sophisticated and complementary techniques to ensure a complete and reliable characterization. Among these, Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA) form a fundamental trio for the in-depth study of rubbers, plastics, and fibers. At APM Laboratory, these methodologies are employed both individually and in combination to provide a comprehensive understanding of the chemical composition, physical properties, and thermal behavior of materials.
By integrating these techniques, we achieve a detailed and multidimensional characterization of polymeric materials. FTIR spectroscopy provides chemical insights, DSC analyzes physical and thermal properties, while TGA focuses on thermal stability and composition. This holistic approach is ideal for detecting defects, optimizing production processes, and ensuring compliance with quality standards.
MASS SPECTROMETRY FOR ORGANIC ANALYSIS
To further enhance our analytical capabilities, APM Laboratory employs mass spectrometry, often coupled with gas chromatography (GC-MS) or liquid chromatography (LC-MS), to identify and quantify organic substances present in or released from samples. The analytes are extracted in a solvent, separated through a chromatographic column, and identified using spectral libraries. This technique is crucial for detecting additives, plasticizers, flame retardants, and degradation products, providing a comprehensive view of the material’s composition.
FTIR SPECTROSCOPY: ADVANCED CHEMICAL IDENTIFICATION
FTIR spectroscopy is an essential tool for identifying polymer types and functional groups within a sample. By analyzing the interaction between infrared radiation and the material’s molecules, this technique provides a “chemical fingerprint” of the polymer.
At APM Laboratory, FTIR analysis is enhanced by an advanced infrared microscope, allowing for the examination of extremely small samples, down to just a few microns. This is particularly useful for analyzing residues, scraps, or contaminants present in minimal quantities, ensuring high-precision analysis even on non-homogeneous materials.
DSC CALORIMETRY: STUDY OF THERMAL PROPERTIES
Differential Scanning Calorimetry (DSC) is essential for analyzing thermal transitions in polymeric materials, such as melting temperature and glass transition. This technique measures the heat flow required to change the sample’s temperature, providing crucial insights into the physical properties and quality of the polymer.
DSC thermograms can reveal the presence of foreign or recycled materials, molding defects, and residual stresses. At APM Laboratory, we utilize state-of-the-art DSC instruments capable of analyzing extremely low temperatures, down to -196°C, enabling detailed studies of polymers that require specific thermal conditions.
TGA THERMOGRAVIMETRY: THERMAL STABILITY ANALYSIS
Thermogravimetric Analysis (TGA) complements the thermal characterization process by measuring mass variation as a function of temperature. This method is fundamental for assessing thermal stability, chemical composition, and the presence of mineral fillers or residues.
By analyzing weight loss during heating, TGA can detect volatile components, plasticizers, or solvent residues, providing valuable insights into material purity and potential applications.
QUALITY ASSURANCE AND REGULATORY COMPLIANCE
All analyses performed at APM Laboratory strictly adhere to national and international standards (UNI, EN, ISO, ASTM, DIN) or specific customer requirements. This ensures reliable, repeatable results, suitable for industrial and research applications.
