Titanium Dioxide (Paper & Laminate Grade)
CAS Number: 13463-67-7
Titanium dioxide (TiO₂) is the most effective white pigment for opacity and brightness in paper manufacturing. It is used in decorative laminates, specialty papers, banknote paper, and high-quality printing papers where maximum opacity at minimum basis weight is required. TiO₂ scatters visible light far more efficiently than any other mineral filler, enabling production of thin, opaque paper grades.
