Details:

CAS 11097-59-9 Mg-Al Hydrotalcite PVC A CPVC Pipes Stabilizer Hydrotalcite

 

Product Description

Hydrotalcite is a layered double hydroxide (LDH) mineral with the general chemical formula [Mg?Al?(OH)??CO?·4H?O]. It is a naturally occurring and synthetic compound widely used as a functional additive in various industries. Hydrotalcite is best known for its application as a heat stabilizer in polymers, especially PVC, and as an acid scavenger. It is also used in pharmaceuticals, catalysis, and environmental applications due to its high surface area, excellent ion-exchange capacity, and thermal stability.
