High-Tg Halogen Free Medium Flow Prepreg
Prepreg: TU-84P MF

TU-84P MF medium flow, halogen-free prepreg consist of optimal resin flow specially formulated for unique purpose bonding application. The special design TU-84P MF medium flow, halogen-free prepreg is appropriate for applying in multiple layer rigid-flex bonding, heat sink bonding and die cavity board application. TU-84P MF medium flow prepreg also provide excellent bonding performance with a variety of polyimide materials and with excellent high Tg, low CTE thermal performance for sequential lamination and lead-free processes.
