Yep "There are many different types of polyimide like there are many different types of epoxies and they have very different properties." http://www.goodfellow.com/static/E/IM30.HTML Inge -----Ursprungligt meddelande----- Från: TechNet [mailto:[log in to unmask]] För Joe Fjelstad Skickat: den 10 maj 2007 18:54 Till: [log in to unmask] Ämne: Re: [TN] SV: [TN] Strange one? 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. 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.
