Silica Sand for Artificial Grass | Natural Sand Infill

Silica sand differs from regular sand as by definition, it must have 95% SiO2 (silicon dioxide) and less than 0.6% iron oxide. Because of its purer composition compared to 'regular' sand – which contains less than 80% SiO2 – it's much less chemically reactive. It is added to artificial turf as infill because it provides a natural feel ...

What Is Silica Sand & How Is It Different From Regular Sand?

Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2).
