Applications & Use Cases
- ▸ Acid scavenger and co-stabilizer in PVC and halogen-containing polymer compounds, neutralizing HCl liberated during processing to prevent discoloration and chain degradation.
- ▸ Costabilizer that improves the heat and color stability of flexible and rigid PVC when used alongside Ca/Zn stabilizer systems, reducing or replacing heavy-metal stabilizers.
- ▸ Catalyst-residue (chloride) neutralizer in polyolefins such as polyethylene and polypropylene, protecting equipment and improving long-term thermal stability.
- ▸ Functional mineral filler and rheology aid in coatings, sealants, and rubber compounds where its layered structure provides barrier and anion-exchange properties.
- ▸ Precursor for layered double hydroxide (LDH) nanocomposites and flame-retardant additive systems in specialty plastics and construction materials.
