2. Meta Grade Sodium Antimonate
Meta Grade is the high performance Sodium Antimonate used mainly for PET, PBT and PA for injection compounds.
Its refractive index of this grade is similar to many kinds of plastics, allowing the original transparency and clear coloring
of the plastics to be closely maintained making it a better alternative to antimony trioxide.
