Flame Retardancy of SUMIKAEXCEL PES

Figure 1 depicts the limiting oxygen index, in order to compare the flame resistance of SUMIKAEXCEL PES to that of other resins.
Furthermore, it is commonly known that the combustion of SUMIKAEXCEL PES produces extremely low amounts of smoke, thus SUMIKAEXCEL PES is often utilized for aircraft interior components.
Figure 2 shows the results of testing conducted by the American National Bureau of Standards to determine the smoke production of SUMIKAEXCEL PES and other resins, during combustion. SUMIKAEXCEL PES also produces minimal amounts of corrosive gases during the molding process, and molded products have minimal outgassing.
