Polyamide 12 with no Tg present
Polyamide 12 with no Tg present
(OP)
I have been doing DSC testing on a polyamide 12. All of the samples are suppose to be the same, but on 2 of the samples there is no glass transition present. I am running the test at 20C/min. The reason I am testing the samples is after the resin has been molded it is sticking to the mold. I think the 2 samples with no Tg present must have come in contact with moisture and this may be the cause of the sticking, but I am not sure. Any ideas would be helpful thank you.

It is so easy!
We mould tonnes pa of PA12 and I cannot recall a "sticking in the mould" problem. PA 12 is never, ever a problem.
I guess you're not in the USA as their usual equivalent is PA610?
