CS Glass powders provide a clean post consumer filler for polymer-based systems where the highest brightness is not required. The fillers impart excellent abrasion resistance and chemical stability to coatings and other polymer systems. Vitro Minerals’ unique processing system and true particle size classification provides consistent product quality for three grades with finenesses covering a range of potential applications: CS-200 (d50 = 12-16 µm); CS-325 (d50 = 10-12 µm); and CS-400 (d50 = 6-8 µm).
