ODPA

ODPA ODPA 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!   Application ODPA is also used to produce polyetherimide thermoplastic resins. A good balance of rigidity and flexibility leads to high toughness, a requirement for these high-performance engineered materials, used in a variety of aerospace, automotive and industrial parts.   Features Chemical Name:ODPA Other Name:Oxydiphthalic Anhydride,OPDA Anhydride Classification:Anhydride Molecule:C16H6O7 Molecule Weight:310.22 CAS NO.:1823-59-2 HS CODE:2909-3000 Standard:Q/82HL05-2004   Product Specification ITEM INDEX Characteristics White or almost white powder, no bad smell Assay ≥99.5% Melting point(°C) 227.0~230.0 Single metal ion (mg/kg) ≤1 Package 25kg/fiber drum Application Making polymer material
