Hydrotalcite, a naturally occurring mineral, belongs to the family of layered double hydroxides (LDHs) with the general chemical formula Mg6Al2(OH)16CO3·4H2O. Synthetic variants, often termed hydrotalcite-like compounds (HTlcs), are engineered to exhibit tunable compositions, where divalent cations (e.g., Mg²⁺, Zn²⁺) and trivalent cations (e.g., Al³⁺, Fe³⁺) form positively charged layers. These layers are balanced by interlayer anions (e.g., CO₃²⁻, NO³⁻, Cl⁻) and water molecules. This unique structure grants hydrotalcite exceptional properties such as high surface area, anion exchange capacity, thermal stability, and adjustable acidity/basicity, making it a material of choice across diverse industries.
Our hydrotalcite superiority stems from three decades of focused R&D and a vertically integrated supply chain. The SK-Quantum™ Synthesis Platform enables precise control over crystallinity and morphology, ensuring batch-to-batch consistency even at industrial-scale production.
Key Applications and Sector-Specific Advantages
» Plastic Industry: Enhancing Performance and Sustainability
In the plastics sector, hydrotalcite serves as a multifunctional additive, primarily acting as a heat stabilizer and halogen scavenger in polyvinyl chloride (PVC) and other halogen-containing polymers. Its layered structure neutralizes hydrochloric acid (HCl) released during PVC processing, preventing degradation and extending product lifespan. Additionally, hydrotalcite improves UV resistance and mechanical strength in polymers like polyolefins.
» Coatings and Inks: Achieving Durability and Aesthetic Excellence
Hydrotalcite is widely used in coatings and inks to improve corrosion resistance, rheology control, and optical properties. Its anion-exchange ability enables it to trap corrosive ions (e.g., chloride), protecting metal substrates in automotive and marine coatings. In ink formulations, it enhances pigment dispersion and reduces settling.
» Building Materials: Fire Safety and Structural Integrity
In construction, hydrotalcite is incorporated into fire-resistant boards, cement composites, and thermal insulation materials. When exposed to heat, it releases water and carbon dioxide, cooling the material and delaying flame spread. It also reduces cracking in concrete by absorbing excess moisture during curing.
» Rubber Industry: Optimizing Processing and Longevity
Hydrotalcite improves the processing efficiency and aging resistance of rubber products such as tires, seals, and hoses. As a vulcanization accelerator, it shortens curing times while maintaining elasticity. Its moisture-absorbing properties prevent blistering during high-temperature molding.
» Cosmetics and Pharmaceuticals: Safe and Effective Formulations
In cosmetics, hydrotalcite functions as a stabilizer, antacid, and delivery vehicle for active ingredients. Its high surface area and biocompatibility make it ideal for sunscreens (as a UV absorber), antiperspirants, and skincare creams. In pharmaceuticals, it is used in antacid tablets to neutralize stomach acid and in drug delivery systems for controlled release.
