MINEX® ST functional fillers are produced from nepheline syenite; a naturally occurring, silica deficient, sodium- potassium alumina silicate. Automated scanning electron microscopy confirms they contain less than one-tenth of one percent crystalline silica. No free crystalline silica is detectable in the mineral complex. All MINEX® ST grades are processed
and sized with rigid adherence to Covia’s QIPSM quality assurance programs. Consistently uniform chemistries, size distributions, and top size controls ensure reliable performance.
