Glass has a fairly low recycling rate due to collection and processing difficulties. Vitro Minerals has developed a variety of post-consumer and post-industrial glass sources and unique processing schemes to make glass powders with excellent particle size control and brightness standards equal to traditional mineral fillers. The resultant glass powders act as cost effective functional fillers in coatings, plastics, adhesives, sealants, and concrete. The powders are available in different glass chemistries in particle sizes from 0.5 microns to 500 microns.
“Glass powders, in addition to being free of crystalline silica, offer a lighter weight, corrosion/abrasion resistant filler for polymer systems that have the added advantage of being recycled content," said Joseph Keating, president of Vitro Minerals.
