Thanks for the history and links. Those are some unnerving stories to be
sure, however I would like to make sure that the baby does not get tossed out
with the bath water.
There are many different types of polyimide like there are many different
types of epoxies and they have very different properties.
We have all seen how metallic lead in electronic solder was vilified based
on the actions of lead salts in paint and lead in gasoline. It is too easy to
begin to slide down that slope if it gets latched onto by marketing types.
I would hate to see polyimde get a similar broad brush treatment metallic
lead has received.
Best,
Joe
