I'm doing the senior project on Material Science and really don't know where to look for this piece of information. The material I'm working on is Polyglycolic acid. Does anyone have any ideas what additives should not be there for it to be considered as medical grade? References would also be helpful.
Thanks in advance.
Medical grade does not only include the additives, but the manufacturing and packaging process as well.
As far as additives are concerned, it can't contain anything that is toxic or hazardous.
You could start by comparing your PGA to Surgicryl a PGA absorbal suture.
I think there is another PGA product called Kurdux (kurdex, curdex, curdux, somthing like that) used for tissue scaffolding, but I've never used it and don't know that much about it - including how to spell it.
