Hi, It’s possible to measure char yield by running the TGA to high temperature under inert atmosphere, where the char can form, and then switching to air atmosphere to burn it. That weight loss can indicate the char yield. However, a more direct method to test flame retardancy would be according to the UL 94 standard. Enjoy your day and kind regards, Denise PTG Eindhoven
Thank you for replying to my comment on your video. I truly appreciate the content you've shared regarding tannic acid (TA). I was wondering if it would be alright to ask a few questions about thermogravimetric analysis (TGA), particularly regarding the data that can be obtained from it. I am also interested in learning more about dynamic TGA and its applications. Thank you once again for your informative content, and I look forward to your guidance.
Your welcome, there are many online resources on the basics of TGA, for example from manufacturers like TA Instruments, Mettler Toledo, Perkin Elmer or Netzsch. What specific question do you have?” Kind regards, Denise PTG Eindhoven
Hi there, hereby the answer to your question: The typical sample size for TGA is around 10-20 milligrams. Shape does not really matter, as long as it fits in the sample tray. The trays you see in the video are 1 cm in diameter. Have a nice day and kind regards, Denise PTG Eindhoven
Hi, The TGA thermogram is from a polyvinyl acetate material. If you have more questions, please feel free to let me know! Have a nice day and kind regards, Denise PTG Eindhoven
The TGA thermogram values are for which compound?
Does TGA can measure the char yield of the substance?, I would like to know if TGA is best testing method of fire retadancy of a sample ?
