This product is used as a replacement for kaolin in the glass fibre manufacturing process. Its inclusion delivers a range of benefits, including:

– less energy consumption / lower CO2 emissions;

– potential for higher yields;

– lower in heavy minerals, arsenic and lead;

– higher bulk density than kaolin, meaning lower transport costs
