Application

Bisphenol A cyanate ester, as an important organic synthesis intermediate, is widely used in the fields of polymer materials and fine chemicals. In polymer synthesis, its bifunctional structure can be used as a crosslinking agent to construct high-performance resins through the reactivity of cyanoxy groups, thereby enhancing the heat resistance and mechanical strength of the materials. 2, 2-bis -(4-cyanatophenyl)propane can be used in fine chemicals to prepare functional dyes or pharmaceutical intermediates.

Bisphenol A cyanate ester can be used as intermediate of medicine and pesticide, as well as printed circuit board, internal materials of aircraft (aerospace and aviation) and radar shield.
