REFINED POWDERS & ABRASIVE PRODUCTS:

ECG provides a full line of refined glass sand additives, polymer fillers and abrasives from recycled glass. These refined sands are 99.9% free from contamination and are used either as additives to convert conventional products into "Green" products or for the benifical properties that recycled glass can inpart. The Environmental Protection Agency (EPA) reports recycled glass abrasives contain no free silica and therefore offer no risk of silicosis. In addition to a moll hardness of 5.5-6, recycled glass sands and powders have sharper, more angular particle shapes, zero perosity and are 10-15% lighter than conventional sand. ECG markets these products in 2000lbs. supersacks or 100lbs bags and 50lbs bags.
