Extracted from a natural mineral, it is a chemically stable aluminum-calcium silicate product. Because it is a natural mineral, rather than a chemical form, it has advantages over silica gel in terms of cost and environmental protection. The content of heavy metals is lower than the limits set by the European Union and the United States. It does not contain acidity and will not cause environmental pollution to soil, river water and air after being used
