What is Hydrotalcite？
hydrotalcite (LDHs), also known as Hydrated magnesium aluminate carbonate, is a layered ionic compound characterized by the assembly of positively charged main layers and interlayer anions through non-covalent interactions. It belongs to a class of inorganic materials with a layered structure. The anion layer is located in the gap between the oxide layers, and attracts the metal ion layer through charge balance, making the layered structure stable.

Application
1. Hydrotalcite can be used as an environmentally friendly flame retardant and a PVC composite stabilizer.
2. Hydrotalcite is used as a slow-release moisturizer in agricultural films, and can produce greenhouse films with high light transmittance, low haze and good moisture retention.
3. Hydrotalcite is used as a multifunctional filler improver for flame retardancy, stabilization, insulation, coloring, and UV resistance of polymer materials such as plastics, rubber, and chemical fibers.
4. Hydrotalcite is used as a raw material for daily chemical products such as dyes, coatings, paints, and cosmetics, and as a flocculant for water purification in dye fabric wastewater treatment.
