Application of 4
4'-Oxydianiline 1. It is one of the
important raw materials for high temperature resistant resins such as
polyimide, polyetherimide, polyesterimide, polymaleimide, and polyaramid;
2. It is also the raw material for the
synthesis of 3,3',4,4'-tetraaminodiphenyl ether, which is the main monomer for
preparing a series of aromatic heterocyclic heat-resistant polymer materials.
3. It is also used as a raw material and
cross-linking agent for high-performance heat-resistant epoxy resin,
polyurethane and other synthetic polymers.
4. At the same time, it is also used in
the production of azo dyes, reactive dyes and perfumes to replace benzidine
which has carcinogenic effects.
Packing: Inner packing aluminum film bag vacuum
packing, outer packing is carton or cardboard barrel, can be packed according
to customer requirements.
According to the
production process, different products are divided into sublimation and
