Alumina-based spherical aggregate "Espal"
Excellent crush resistance! Contributes to improved yield during recycling (reduction of waste) and enhancement of the work environment.
"Espal" is an alumina-based spherical aggregate that can be used as a substitute for zircon sand and chromite sand due to its high thermal conductivity and significant heat absorption capacity. Its round and nearly spherical particle shape provides good flowability of the sand, improving the filling ability and strength of the mold, contributing to the improvement of casting surface roughness and prevention of galling. Compared to silica sand, it clearly exhibits a higher strength level and is effective in preventing gas defects by reducing the amount of resin added. [Features] ■ Round particle shape ■ Dense particle surface with minimal irregularities and smooth ■ Excellent collapsibility ■ Low thermal expansion rate ■ Excellent crush resistance ■ High thermal conductivity and refractoriness *For more details, please download the PDF or feel free to contact us.
