SAC Lead material — lab-validated
Strongly acidic cation exchanger
Sulfonic acid groups on a silica framework
Softening, demineralization, and solid-acid catalysis.
Products
One chemistry, the full range
Silexa’s silica platform spans the complete acidity spectrum that water treatment and process industries depend on — a platform in development, not an off-the-shelf catalogue.
Strongly acidic
Strongly basic
- SAC
- WAC
- WBA
- SBA
WAC In development
Weakly acidic cation exchanger
Carboxylic acid groups on a silica framework
Dealkalization and selective hardness removal.
WBA In development
Weakly basic anion exchanger
Amine groups on a silica framework
Removal of strong acids and organic contaminants.
SBA In development
Strongly basic anion exchanger
Quaternary ammonium groups on a silica framework
Silica and CO₂ removal, full demineralization, polishing.
The strongly acidic cation exchanger leads the platform and is validated at laboratory scale. The remaining classes build on the same framework chemistry and are in active development.
Materials
Engineered as particles, ready for columns
Silexa materials are produced as porous particles designed for the same fixed-bed columns and process steps that polymer resins occupy today — replacement, not re-engineering.
