Ground Glass Powder
Quick Overview
SSS Ground Glass Powder is made from 100% recycled glass occurring in laminated glass (primarily automotive windshields). The product is gray colored powder with a uniform particle size distribution. SSS Ground Glass Powder is amorphous and contains no crystalline silica and provides a clean post-consumer filler for polymer-based systems. This filler impart excellent abrasion resistance and chemical stability to coatings and other polymer systems. SSS Ground Glass Powder processing system provides consistent product quality with fineness covering a range of potential applications. Product is screened and shows average size particles of Mesh 325.
