The occurrence of fire is often caused by the material being exposed to high temperature or open fire, so the thermal stability of the material plays a very important role in the practical application of the material. Alfa Chemistry provides thermal analysis services for flame retardant materials, and is committed to solving the challenges faced by customers in thermal stability research and flame retardant mechanism research.
Thermogravimetric Analysis (TG)
Thermogravimetric analysis mainly studies the thermal stability and composition of flame retardant materials, by controlling the temperature rise through program settings to measure the relationship between the quality of flame retardant materials and temperature. Important parameters such as thermal decomposition temperature, weight loss times and component proportions of flame retardant materials can be obtained from the results of thermogravimetric analysis.
DSC and DTA
DSC (Differential Scanning Calorimetry) and DTA (Differential Thermal Analysis) mainly study the energy absorption and release of flame retardant materials under elevated temperature conditions. Both can reflect the absorption and release of energy caused by physical or chemical changes of flame-retardant materials at high temperatures, and can reflect information such as phase transition temperature, glass transition temperature, and decomposition temperature of flame-retardant materials.
Instrument Combined Detection
The combined use of thermal analysis instruments can combine the mass changes, energy changes, volatile substances, etc. in the reaction process to analyze the physical and chemical changes that occur in flame retardant materials during the process of increasing temperature. Alfa Chemistry provides instrument combined detection services, such as TG-FTIR, TG-DSC, TG-MS, TG-FTIR-MS, etc.
Thermal Analysis Kinetics
Thermal analysis kinetics is a method of applying thermal analysis techniques to study the physical properties of substances and the rate and mechanism of chemical reactions. By analyzing the obtained experimental data with the help of various mathematical methods (integration method, differential method, numerical solution method, etc.), the kinetic parameters and mechanism functions of the corresponding thermal decomposition reaction can be obtained, such as activation energy (Ea), preexponential factor (A), solid reaction rate (k) and conversion (α), etc.
