BLAST MITIGATION is the process of making an explosive blast less severe by selecting materials based on resistance, attenuation, and absorption of the blast effect.
The natural micro structure of a pumice stone—a foamed-stone web of air-filled vesicles—classifies it as a cellular solid. Blast Mitigator™ works through attenuating the peak over pressure from a blast through the systematic disintegration of the pumice stones.
The manufacturing process simply involves combining pumice aggregate with an epoxy binder and sandwiching it between rigid panels or flexible sheets. The loose, granular nature of pumice makes it ideal for use in these types of flexible-sheet blast mitigating assemblies. Blast Mitigator can also be used as a loose fill in the annular space of a double-wall containment construct. An example of this type of application is the SLAM-ER CNU-595 munitions container (for SD rockets) consisting of an aluminum shell filled with four inches of pumice.
Under magnification, pumice blast media shows its angular, interlocking shapes and foamed glass stone nature.

PLEASE READ THE SHIPPING NOTES BELOW BEFORE PLACING AN ORDER.
SHIPPING NOTESInformation about turn-around times, auto-calculated shipping, obtaining shipping rates for large orders, more.
1 | For weight-quantities over 20 lbs, shipping cost savings are typically realized by ordering a full-sized production bag (boxed) instead of multiple 20 lb. boxes.

3 | The shopping cart system occasionally glitches on an address and throws up an “order can’t be shipped to your address/location” (or similar) error message. Not true. We ship almost anywhere. Contact us at fc@hesspumice.com and we’ll take care of you.
