ISO 11358-2 Decomposition Behavior by TGA
The Thermal Gravimetric Analysis (TGA) method described in ISO 11358-2 is a critical technique used to assess the thermal stability and decomposition behavior of materials. This service involves determining the temperature at which a material starts to decompose, as well as the rate of mass loss during this process. Understanding these parameters is essential for quality managers, compliance officers, R&D engineers, and procurement professionals who need reliable data on material performance under heat.
The TGA method measures changes in mass with temperature, providing insights into the thermal stability, purity, and composition of materials. This service specifically targets additives used in additive manufacturing (AM) processes, including polymers, composites, and other advanced materials that undergo complex processing conditions during 3D printing.
The testing process begins with careful selection and preparation of the specimen, ensuring it represents the material accurately without introducing external variables. Specimens are heated under controlled atmospheres to simulate real-world processing environments, which can range from inert gases like nitrogen to oxidizing or reducing atmospheres depending on the material type.
During the test, precise temperature control is maintained, and mass changes are monitored with high sensitivity. The results provide a detailed decomposition profile, including onset temperatures (Tg) and peak decomposition temperatures (Td). These values help in understanding how materials behave under heat stress during AM processes such as powder bed fusion or direct metal laser sintering.
The accuracy of the TGA method is enhanced by using high-precision instruments that ensure consistent results across multiple samples. The equipment used adheres to international standards, ensuring compliance with global quality requirements. This service not only supports regulatory compliance but also aids in optimizing manufacturing processes for better product performance and reliability.
The decomposition behavior of materials can significantly impact the final properties of parts produced using AM technologies. For instance, understanding how a polymer decomposes at different temperatures helps in selecting appropriate processing parameters to avoid degradation during the build process. Similarly, knowledge of metal alloy decomposition aids in optimizing cooling rates to prevent distortion or cracking.
Compliance with ISO 11358-2 ensures that materials used in AM are robust and reliable under real-world conditions. This service supports industries ranging from aerospace to automotive, where precision and reliability are paramount. By providing detailed thermal decomposition data, this testing method helps manufacturers make informed decisions about material selection and process optimization.
The scope of this testing extends beyond basic decomposition behavior; it also includes the identification of volatiles released during heating, which can be critical for understanding potential environmental impacts or health hazards associated with AM processes. The insights gained from TGA testing are invaluable for R&D teams looking to innovate and improve material formulations.
In summary, ISO 11358-2 Thermal Gravimetric Analysis is a vital tool in ensuring the quality and reliability of materials used in additive manufacturing. It provides essential data on thermal stability that can be leveraged across various industries to enhance product performance and meet stringent regulatory requirements.
