Thermal Analysis


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 systemInfrared heating technology system
Temperature rangeFrom room temperature to 1200 °C
Linear control heating rate0.1 ~ 500 °C
Impact heating rate> 1500 °C/min
  • Applicable scope of the instrument
    1. 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.
    2. Can test the constant temperature kinetic parameters of the material.
    3. Can test the temperature-changing kinetic parameters of the material.
    4. 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
    1. The application range is very wide, especially the research and development of materials, performance testing and quality control.
    2. 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)

Drive motorMagnetic drive motor to ensure precise control of stress in a wide range of force
ModesConstant strain mode, multiple frequency mode, creep/stress relaxation mode, multiple stress/strain mode, controlled stress/strain rate mode.
  • Applicable scope of the instrument
    1. It can operate in the temperature range of -145 ~ 600 °C at a heating rate of 20 °C/min.
    2. The property changes of samples can be determined based on the changes in seven experimental variables: temperature, time, frequency, stress, force, displacement and strain.
    3. Suitable samples can be solids, films, fibers, gels or viscous liquids.
    4. 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
    1. TMA is often used to study the expansion or contraction of materials.
    2. TMA is one of the more important thermal analysis methods, and it is a good supplement to perfect DSC, TGA and DMA methods.
    3. TMA allows you to determine the expansion coefficient and softening temperature.
    4. It can measure relaxation effects that are often undetectable by DSC.
