Alfa Chemistry Fluoropolymers uses thermal analysis to optimize our products, work with our customers to solve their problems, and develop the best formulations in an efficient, professional and high-quality way. The following are some of the equipment and methods we use to evaluate and optimize our materials.
Thermogravimetric Analyzer (TGA)
- Main performance indicators
| Heating system | Infrared heating technology system |
| Temperature range | From room temperature to 1200 °C |
| Linear control heating rate | 0.1 ~ 500 °C |
| Impact heating rate | > 1500 °C/min |
- Applicable scope of the instrument
- To test the decomposition process of the material within the set temperature range, it is necessary to pay attention to the initial decomposition temperature and maximum decomposition temperature.
- Can test the constant temperature kinetic parameters of the material.
- Can test the temperature-changing kinetic parameters of the material.
- The important parameters of the material include the initial decomposition temperature (T5%), maximum initial decomposition temperature (Tmax), residual mass (wt%), etc.
Differential Scanning Calorimeter (DSC)
- Applicable scope of the instrument
- The application range is very wide, especially the research and development of materials, performance testing and quality control.
- The characteristics of materials, such as glass transition temperature, cold crystallization, phase transition, melting, crystallization, product stability, solidification/crosslinking, oxidation induction period, etc., are all DSC research fields.
Dynamic Thermomechanical Analyzer (DMA)
- Main performance indicators
| Maximum force | 18 N | Frequency Range | 0.01 ~ 200 Hz |
| Minimum force | 0.0001 N | Dynamic sample deformation range | ±0.5 ~ 10,000 μm |
| Force resolution | 0.00001 N | Temperature range | -160 ~ 600 °C |
| Strain resolution | 1 nm | Heating rate | 0.1 ~ 20 °C/min |
| Modulus range | 103 ~ 3×1012 Pa | Cooling rate | 0.1 ~ 10 °C/min |
| Modulus accuracy | ±1% | Constant temperature stability | ± 0.1 °C/min |
| Tanδ sensitivity | 0.0001 | Time/temperature overlay | Yes |
| Tanδ resolution | >0.00001 |
| Drive motor | Magnetic drive motor to ensure precise control of stress in a wide range of force |
| Modes | Constant strain mode, multiple frequency mode, creep/stress relaxation mode, multiple stress/strain mode, controlled stress/strain rate mode. |
- Applicable scope of the instrument
- It can operate in the temperature range of -145 ~ 600 °C at a heating rate of 20 °C/min.
- The property changes of samples can be determined based on the changes in seven experimental variables: temperature, time, frequency, stress, force, displacement and strain.
- Suitable samples can be solids, films, fibers, gels or viscous liquids.
- Use interchangeable tools to measure a variety of properties, including: modulus, damping, creep, stress relaxation, glass transition, and softening point.
Thermomechanical Analysis (TMA)
- Applicable scope of the instrument
- TMA is often used to study the expansion or contraction of materials.
- TMA is one of the more important thermal analysis methods, and it is a good supplement to perfect DSC, TGA and DMA methods.
- TMA allows you to determine the expansion coefficient and softening temperature.
- It can measure relaxation effects that are often undetectable by DSC.
