Physical Properties:
(ODPA)4,4'-Oxydiphthalic Dianhydride is white or off-White powder,melting point is 227 - 229 degrees Celsius.

Application:
Widely used to produce high performance composite materials, foam, adhesive, moulded products, film, microelectronics, gas separate membrane, that exhibit excellent processability,mechanical property,electrical insulation, thermal oxidative stability, radiation resistance, chemical resistance, wear resistance and flame retardancy with low smoke generation.

Act as an epoxy latent curing agent for microcapsulizing.

Reinforced, modified or co-polymerized grade ODPA can be applied for foam plastics, moulded products, fiber, coatings, adhesives, enamel-insulated wire and precision parts where excellent extreme temperature resistance is required.
