Limiting oxygen index and smoke production

To compare flame retardancy with other resins, the limiting oxygen index is shown in Figure 3-4-1. Furthermore, SUMIKAEXCEL PES is known for its extremely low smoke emission, and is used in aircraft interior parts. Figure 3-4-2 shows the results of smoke emission tests conducted by the National Institute of Standards and Technology (NIST) in comparison with other resins.

Gas evolution

SUMIKAEXCEL PES is a resin that generates very little corrosive gas during molding, and very little outgassing from molded products.

Combustion characteristics

The UL 94 Flammability Standard, developed by UNDERWRITERS LABORATORIES INC., is a system for classifying plastic materials based on their resistance to combustion.
The UL file number for SUMIKAEXCEL PES is E249884.

Color: Color tone (ALL: all colors, NC: natural color, BK: black, RD: red, WT: white)
Flame Class: Flammability class
Relative Thermal Index (RTI): Temperature index
Hot Wire Ignition (HWI): Hot wire ignition resistance
High Ampere Arc Resistance (HAI): High current arc resistance
High Voltage Arc Tracking Rate (HVTR): High voltage arc tracking rate
D495: Arc resistance test
Comparative Tracking Index (CTI)
PLC: HWI, HAI, HVTR, D495, CTI are displayed as Performance Level Categories (PLC) grades.
