Limiting Oxygen Index and Smoke Emission
Figure 3-4-1 shows the Limiting Oxygen Index for comparing flame retardancy with other resins. SUMIKAEXCEL PES is known to have low smoke emission and is even used for parts inside aircrafts. Figure 3-4-2 shows the smoke emission test results by The National Institute of Standards and Technology (NIST) compared with other resins.

Outgas
SUMIKAEXCEL PES generates very little corrosive gas during the molding process, and also causes very little outgassing from the moldings.
Figure 3-4-3 Molding Temperature and Outgas from Moldings
(Dumbbell test pieces molded at each temperature were heated at 120°C for 20 hours, and the outgas was analyzed using head space gas chromatograph.)
UL Standard
The UL 94 flammability standard, established by Underwriters Laboratories Inc. is a system for classifying plastic materials based on their flammability resistance. The UL file number for SUMIKAEXCEL PES is registered as E249884.
