  • Applications

    Magnesium benzoate is used as a heat stabilizer for plastics and polymers, particularly PVC, to improve thermal stability and product longevity. It is also employed as a processing additive in polymer formulations to enhance processability for coatings and inks. The salt can act as a chelating agent to sequester metal ions in formulations, helping to reduce metal-catalyzed degradation. It serves as an intermediate in organic synthesis for preparing benzoate-derived compounds.
