- Conclusions:
- Sodium p-styrenesulfonate did not generate powder dust explosioin.
Sodium p-styrenesulfonate is not explosive. - Executive summary:
The explosibility of sodium p-styrenesulfonate was evaluated by powder dust explosion property.
The explosibility of sodium p-styrenesulfonate was very low under test conditions.

* ○: Explosion △; Explosion ×; Not explosion
○ Explosion: Upper part of filter paper was broken and fire was spread all of the explosion tube.
△ Explosion: Upper part of filter paper was not broken, but the flame was rose up above 100mm.
×Flame was less than 100 mm or only spark between electrodes was observed.
The test repeated 5 times at the same concentration, the lowest limiting explosion powder dust concentration was determined if even one time explosion was observed.
2. Limiting oxygen concentration
Limiting Oxygen Concentration: 17.5 %
○ Explosion : Explosion pressure > 0.5 kgf/cm2
△ Explosion : 0.1 kgf/cm2≦Explosion pressure≦0.5 kgf/cm2
×Non-explosion : Pressure rise < 0.1 kgf/cm2or equal to the blowing pressure.
