100% Recycled Crushed Glass Blast Media Technical Data What is it? Crushed glass blasting media is an engineered “sandblasting” media manufactured from 100% Recycled Bottle Glass. Crushed glass can be used as a direct replacement for most hard abrasives, including silica-sand, Olivine, lava, coal slag (aka Black Beauty), and aluminum oxide. Crushed Glass is approved for use in numerous federal and state government agencies, and military branches. It is non-hazardous, non-toxic and completely inert, so is safe to use around water. Glass dust is classified by OSHA/NIOSH as only “nuisance” dust because it contains less than 1% free silica. Glass also does not contain virtually any of the OSHA identified Heavy/Toxic Metals associated with slags and some other mineral abrasives such as Olivine. Lastly, since glass is translucent, visibility and productivity are significantly improved when compared to a blast environment using traditional hard abrasives. How Can Glass be Silica-free? Recycled bottle glass is chemically known as Amorphous Aluminosilicate. Free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting media. Silica-sand dust in its natural state has an “open” crystalline structure that has the capability of sticking to lung tissues. When this happens, the likelihood of developing a serious respiratory disease called Silicosis increases. Because our recycled glass blast media is amorphous, its crystalline structure is “closed,” which makes it impossible to physically stick to human lung tissue. When a person is exposed to amorphous glass fines or dust, the body will expel the dust as it would any other type of natural dirt. Benefits of Glass Blasting In addition to worker safety benefits, crushed glass delivers a natural, whiter metal finish than many other sandblasting abrasives, and significantly decreases embedment issues—up to 5 times less than slag blast media. Glass works great for removing thick, tough coatings, and numerous surface preparation applications—glass can create a profile of up to 4 mils on hardened steel. Glass is versatile, and can be used as a dry blasting media or combined with water for use in slurry blasting machines. Qualified for Use Crushed glass has been added to the qualified products list by the US Navy. Crushed glass is qualified under MIL-A-22262-B, Amendment 2–Abrasive Blasting Media for ship hull blast cleaning. Based on toxicological safety evaluations by the Naval Environmental Health Center (NEHC), Crushed Glass Grit can be safely used for its intended purpose. The addition of crushed glass to QPL includes 12-30 mesh (CBM 1230); and 30-70 mesh, (CBM 3070). SAVE MONEY TOO! Crushed glass is less dense than other sandblasting media. This means greater productivity due to more blast time between pot refills AND less material will be used, which reduces both disposal and media costs.
