You know, something else was brought up on this forum not long ago. I almost forgot what I should
have remembered concerning delta Tg.

I know it's a long shot, but you might determine how well your supplier, and its supplier, effects
cure - especially with different materials or those MLB constructions with juicey or not so juicey
resin contents.

You can look back to December, I think, and see most folks don't allow in excess of 4 degrees C.
variance in Tg.

Again it's a long shot, but you might check if either DSC or TMA testing has been done to see.
