Usage

1). It is one of the important raw materials for new specialty engineering plastics such as polyimide, polyetherimide, polyester imide, polymaleimide, polyaramid, and other high-temperature resistant resins;

2). It is also a synthetic 3,3 ‘, 4,4’-tetra-amino diphenyl ether, which is the preparation of a series of aromatic heterocyclic heat-resistant polymer materials, the main monomer.

3). It is also used as high-performance heat-resistant epoxy resin, polyurethane and other synthetic polymer raw materials and cross-linking agents.

4). Also used to replace the carcinogenic benzidine production of azo dyes, reactive dyes spices, and other fields. Currently with diaminodiphenyl ether as the raw material has been developed red, red, sand red, yellow-brown, green, gray, blue, orange, black and other different levels of direct dyes can be used for silk, wool, cotton, Ma, and another fabric dyeing, color fastness, and exhaustion rate and other aspects are superior to the benzidine dye.
