Types of TGA Testing
TGA testing is usually categorized into three groups based on the heating method:
- Isothermal (Static) TGA Testing: This approach maintains a steady temperature while tracking sample weight with time. It is especially valuable for investigating long-term stability and slow thermal reactions.
- Quasistatic TGA Testing: The temperature of the sample is gradually increased between intervals of constant temperature. This enables extensive investigation of how a material's mass varies at different temperature points.
- Dynamic TGA Testing: This method involves increasing the sample's temperature linearly, allowing for continuous examination of material behavior across a wide temperature range.
Applications and Materials Suitable for TGA Testing
TGA analysis is an adaptable analytical technique that can be used in a wide range of materials.
- Polymers (thermoplastics, thermosets, elastomers, composites, etc.)
- Organic materials
- Metals
- Ceramics
- Fluids
TGA's versatility makes it an important tool in polymer production, plastics, medicines, general manufacturing, and metal oxidation.
Capabilities of TGA Analysis
TGA can measure material characteristics, including water loss, solvents, and plasticizers.
- Loss of water, solvents, and plasticizers
- Decarboxylation
- Thermal decomposition
- Oxidation
- Weight percentages of fillers, contaminants, and ash
- Metallic catalytic residue on carbon nanotubes
Specific Applications of TGA in Various Industries
Thermal Stability in Polymers: TGA can identify temperature limits for polymer stability, assisting manufacturers in anticipating potential performance concerns under harsh environments.
Quality Control Testing: TGA ensures consistency and purity of materials, crucial for product quality and process control.
Residue Analysis After Oxidation and Combustion: Identifies inorganic filler content in composites and monitors metal oxidation patterns.
Kinetic Analysis: TGA data can anticipate material behavior under various heat conditions, offering valuable data on chemical process mechanisms.
