Application field:
1. It is one of the important raw materials to heat-resistant resin as new type engineering plastics polyimide, polyetherimide, polyester-imide, poly-maleimide and polyamides. It is also the raw material to synthesizing 3, 3 ', 4, 4' - tetraminodiphenyl ether, which is the main monomer to produce a series of heteroaromatic heat-resistant of polymer materials.
2. It is also used as the raw materials and crosslinking agent for synthetic polymer as high-performance heat-resistant epoxy, polyurethane, etc. It is also used for alternative to benzidine which has carcinogenic effect to produce of azo dyes, reactive dyes and spices.
3. At present, different color levels direct dye as dark red, bright-red, sand red, brown, green, gray, blue, brilliant orange and black have been developed, which can be used for the dyeing of silk, wool, cotton, hemp fabrics and its color fastness and exhaustion degree are better than benzidine dyes.
4. As China's industry technology has been promoted, performance requirements for corresponding materials have been increasingly high, which greatly promoted the increasingly maturity and popularization of domestic polyimide product development, increasing completion of specifications and varieties, and ODA as new material monomer will be highly valued increasingly. Application area extension leads to rising in ODA demand and output is also increased year by year.
