Chemistry and Technology of Cyanate Ester Resins : Springer : 9789401045773 : 9401045771 : 03 Oct 2013 : After epoxy resins and polyimides, cyanate esters arguably form the most well-developed group of high-temperature, thermosetting polymers. They possess a number of desirable performance characteristics which make them of increasing technological importance, where their somewhat higher costs are acceptable. The principal end uses for cyanate esters are as matrix resins for printed wiring board laminates and structural composites. For the electronics markets, the low dielectric loss characteristics, dimen­ sional stability at molten solder temperatures and excellent adhesion to conductor metals at temperatures up to 250°C, are desirable. In their use in aerospace composites, unmodified cyanate esters offer twice the frac­ ture toughness of multifunctional epoxies, while achieving a service tem­ perature intermediate between epoxy and bis-maleimide capabilities.
