Hello David:
After a 4 month wait I've received a batch of 58mm cores claiming to
be 3C90, but according to the catalogue they have the wrong colour
code. These are white (pos 3C11) not blue/white for 3C90.
The way to confirm is to calculate the Al value and compare to the
data on 3C90 3C85 3C11 etc materials. Unfortunately 3C90 is not
listed in my old data book.
You'll find the specs at:
