Hydrotalcite

Hydrotalcite is a white mineral having a layered structure found in nature with a general chemical formula of Mg6Al2(OH)16CO3.4H2O. 

Hydrotalcites are very effective acid scavengers due to their exceptional anion-exchange properties. Hydrotalcites have greatly enhanced the performance of Ca/Zn-based stabilizer systems, due to their features of environmentally friendliness and non-toxicity. 

Hydrotalcites  particularly have a major role in the development of stabilizers used in the production of rigid PVC window profiles and flexible PVC automotive cables for high temperature applications.
