ODPA also named oxydiphthalic anhydride or odpa anhydride, is a solid, melts in the range of 225-229 °C, offering a greater degree of flexibility than other commercial dianhydrides. It also is somewhat less reactive than BTDA.  ODPA has largely been used in polyimides and much less so in epoxies. It imparts special performance properties in free films and in FCCL production for high-end personal electronic devices.Contact us to get more information!
