Hi Valerie, Isola wants you to 'register'--a process that takea more than a day. http://www.isola-group.com/en/products/name/detail.shtml?47——does not give you Tg(TMA) [the most important, only Tg(DSC)] TE(50->288) instead of the standard TE(50->260), and a Td for which it is not clear whether it refers to 1% or 5% weight loss; if you try to get to ISxxx, e.g. IS410, you get Tg(DSC)], TE(50->260) but CTE(x,y)=11-13 ppm/C—which cannot possible be correct, and the same Td uncertainty. http://www.isola-group.com/en/products/CompatibleLaminate.pdf ——is totally inadequate as far as properties is concerned.
