Borden <strong>Chemical</strong> Black Phenolic Resin (Durite SD-52SS) Test Results<br />
Properties Results<br />
Kst<br />
165 bar-meters per second<br />
MIE 3 millijoules<br />
MEC 50 gram per cubic meter (g/m 3 )<br />
PBD<br />
Moisture content as tested<br />
No ignition observed (when subjected to<br />
discharge of up to 45 kilovolts for 60 seconds)<br />
1.2 weight percent (material was dried at 75ºC<br />
for 3 hours)<br />
These tests established that—with confinement <strong>and</strong> in the presence of a suitable ignition source—dust<br />
particles of the phenolic resin will explode when suspended in air in adequate concentrations.<br />
Test data from the resin samples were also compared to the explosion characteristics of other common<br />
combustible dusts—namely, Pittsburgh coal dust, polyethylene dust, <strong>and</strong> cornstarch. Figure 14 shows<br />
that the Borden <strong>Chemical</strong> black phenolic resin used at <strong>CTA</strong> has a higher Kst value than the other dusts.<br />
