FTIR charts, what`s the material?
zgryzik:
Hello!
I am new here. I have a huge problem, on my university I received two FTIR charts I think they`re some sort of polyamides, but I am not sure at all.
Is there any possibility for you to help me figuring out what those materials are?

2.https://ibb.co/djFRbV
I have also the DSC chart
for the 1st https://ibb.co/btoRAq
for the second https://ibb.co/c2QpVq
Thank you so much!

You have to show an attempt at answering the question before receiving help, that's a forum rule. What do you think the spectra tell you?
Are these materials you have made yourself and got analysed, or are they some random spectra you were given as an exercise?
zgryzik:
The FTIR should tell me what my material is. The DSC shows the two peaks instead of one. That probabelly means, that it`s some sort of copolymer, or the first peak is caused by the fiber glass.
I receive this material on my studies and I have to diagnoze what is that.
I also burnt my material in order to compare it to other. The fire test of my material match the Polyamid almost 100%, but it doesnt burn outside of the flame (the clear polyamide burns).
So I guess, there is a lot of fire retardant inside.

I also found characteristic absorbtions of the IR, but I am not sure, how to use it properly...

You didn't say anything about fiberglass or fire retardant!
I think the first one is Nylon 6,6. (Google "Nylon 66 IR spectrum".) I'm not sure about the second, but 2299 suggests an isocyanate (not on your list!).

Do You see any other characteristic peak on the second material FTIR? C-O? N-O?
