FEEDEX FEF Sleeves
a highly exothermic fluoride emission free sleeve
FEEDEX FEF, a unique fluoride emission free, low VOC highly exothermic, high strength feeder sleeve material, ideal for high pressure casting, to support greensand foundries committed to reducing environmental impact and costs
Case study
Case study of a ductile iron casting for an agricultural machine, showing how the application of FEEDEX FEF VAK sleeves led to sound castings and reduced disposal costs through the avoidance of fluoride contamination of the sand system.

Fluoride compounds have been used in foundries since the 1950s to initiate exothermic reactions in aluminum. Recently, there has been increased focus on fluorides, particularly their presence in feeder sleeves. Concerns include their impact on casting integrity and environmental legislation regarding fluoride disposal.
To address these issues, a range of fluoride-emission-free formulations have been developed, providing the same performance as their conventional counterparts. In order to achieve these results extensive research and trials have been carried out.
