Low Expansion Artificial Sand "NE Sand"
The free silica content is less than 1%, and dust generation during work is extremely low!
"NE Sand" is a low-expansion artificial sand with a rounded shape that has almost no fine powder adhesion due to special grinding treatment. It features a low thermal expansion rate, is hard (Mohs hardness: 7.5, while silica sand is 7), and contains less than 1% free silica, resulting in extremely low dust generation during work. Examples of use include aggregates for resin-coated sand, roofing materials, base materials, heavyweight aggregates, and burial applications. 【General Characteristics (Representative Values)】 <Chemical Composition> ■SiO2: 51.9 ■Fe2O3: 8.2 ■Al2O3: 3.0 ■MgO: 29.8 ■CaO: 4.9 *For more details, please download the PDF or feel free to contact us.
