Product Introduction
4,4'-Oxydianiline, is also known as 4,4'-ODA and 4,4'-Diaminodiphenylether, due to its structure containing two active amine groups, it can efficiently react with acid anhydrides to form stable imide bonds, while also can impart excellent thermal stability and mechanical properties to polyimides, which making it an ideal monomer for synthesizing high-performance polyimides.

Products Feature
Our production process holds independent intellectual property rights, and our 4,4'-ODA has high purity and stable quality. The polyimide synthesized from it as monomers possess outstanding properties such as resistance to high and low temperatures, high strength and modulus, and high electrical insulation. It can be used to produce polyimide films, high-temperature resistant engineering plastics, matrix resins for composite materials, high-temperature resistant adhesives, fibers, and foams, and is also widely used in aerospace, electrical insulation, liquid crystal displays, high-speed railways, satellites, microelectronics, military products, and other fields.
our products advantages
Hight quality& High Melting Point & Low content of Heavy Metals & Uniform particle size distribution
Hight quality
The industry standard for content is ≥99.6%. The test results of our products are all ≥99.8%. High-purity recrystallization 4,4'-OXYDIANILINE generate more homogeneous compounds during the polymerization reaction, resulting in better uniformity of the formed films.
High Melting Point
Our 99.8% min Recrystallization 4,4'-OXYDIANILINE has a higher content and a higher melting point than those of our competitors. A higher melting point leads to better polymerization results when combined with other monomers.
Low content of Heavy Metals
Excessive metal ions will affect the dielectric properties and giant insulating performance of the final film. Therefore, the microelectronics industry has very strict requirements for the metal content. The main metal contents of our ODA have basically not been detected ,we can provide the SGS report.
Uniform particle size distribution
If the content of fine powder is too high, it is prone to accumulate on the stirrer and affect the stirring effect, thereby damaging the uniformity of the film polymerization.
The particle size of our ODA is uniform, and the contents of ultra-long crystals and micro-powders are all controlled at a relatively low level. There is no phenomenon of adhesion.
