I found such article. Maybe my material is connected with the PBT, not PA as I thought?

mjc123:
PBT looks a good shot. It would fit most of the ir peaks except 2300, and also the DSC melting peak.

zgryzik:
What the 2300 peak might be? Cant find anything here :http://www2.ups.edu/faculty/hanson/Spectroscopy/IR/IRfrequencies.html

And the other  problem is : the melting point of PBT is about 220 while my material has 250. What might cause such difference? Glass fiber? Fire retardant?

wildfyr:
You sure 2300cm-1 isn't O2 from the air? Happens when someone is breathing nearby as it's poorly backgrounded

zgryzik:
Do You think so, Sir?
