PURAL MG

PURAL MG 70 is aluminum magensium hydroxy carbonate. It has a 70:30 MgO:Al2O3 ratio. Hydrotalcites have a double-layered metal hydroxide structure consisting of magnesium and aluminum hydroxide octahedrons interconnected via the edges. Additional interstitial anions between the layers compensate the charge of the crystal and determine the size of the interlayer distance (basal spacing).

PURAL MG 30 is aluminum magensium hydroxy carbonate. It has a 30:70 MgO:Al2O3 ratio. Hydrotalcites have a double-layered metal hydroxide structure consisting of magnesium and aluminum hydroxide octahedrons interconnected via the edges. Additional interstitial anions between the layers compensate the charge of the crystal and determine the size of the interlayer distance (basal spacing).

PURAL MG 63 HT is a hydrotalcite product. It may be used in the manufacture of plastic materials and articles, and is approved by the FDA for use as a component of polymeric food packaging. Consequently, PURAL MG 63 HT may properly be considered GRAS when used as a polymer additive.
