Hydrotalcite is a layered double hydroxide, widely used as an acid absorbent due to its unique layered structure and excellent acid absorption performance. The following are the roles and advantages of hydrotalcite in acid absorbents:

Acid absorption performance

Efficient absorption of hydrogen chloride
Mechanism of action: The layered structure of hydrotalcite can effectively absorb and neutralize the hydrogen chloride (HCl) produced during PVC processing, thereby delaying the degradation of PVC.
Acid absorption ability: Hydrotalc has efficient acid absorption ability, which can stably absorb acidic gases under high temperature conditions, significantly improving the stability of the material.
