What is the significance of TGA test for silicone kitchenware?
TGA (thermogravimetric analysis) test has the following reference significance for silicone kitchenware:
Thermal stability evaluation
TGA test can measure the mass change of silicone at different temperatures, help determine its thermal decomposition temperature, evaluate its stability at high temperature, and ensure that it will not decompose or release harmful substances during cooking or heating.
Material purity detection
TGA test can detect the volatile components or additives in silicone to ensure the purity of the material and avoid the migration of harmful substances into food.
Service life prediction
The degradation of silicone at high temperature can be analyzed by TGA test, which can predict its service life and help determine whether it needs to be replaced after long-term high-temperature use.
Quality control
TGA test can be used for quality control in the production process to ensure that the thermal properties of each batch of silicone materials are consistent and meet safety standards.
Safety verification
TGA test can verify whether silicone will produce harmful gases at high temperature to ensure its safety in high-temperature cooking environment.
Material optimization
TGA test results can provide data support for material improvement and help develop more high-temperature resistant and safer silicone materials.
In summary, the TGA test provides an important reference for the thermal stability, purity, service life, safety, etc. of silicone kitchenware, ensuring that it meets food safety standards.
