SEMITI A101 vs Chemours Ti-Pure R-104
SEMITI A101 is anatase paper-grade; Ti-Pure R-104 is rutile paper-grade. Different crystal forms — choose by paper application.
For specialty paper applications, the crystal form choice matters. Anatase (SEMITI A101) is softer, less abrasive on calender rolls, and 25–30% cheaper. Rutile (Ti-Pure R-104) has higher refractive index for ultimate opacity at low loading. Choose by paper grade.

Bold amber indicates the column with the stronger value on that line.
When to choose which
- →Moderate opacity paper (6–12% loading typical)
- →Cost-sensitive specialty paper
- →Equipment-life-conscious mills (anatase has less calender wear)
- →High-opacity decor paper at 30%+ loading
- →Premium HPL overlay paper requiring ultimate opacity
Drop-in substitution
Pricing context
Anatase A101 lands at half the cost per kg of rutile R-104; rutile delivers more opacity per kg. Compare cost-per-unit-opacity for specific paper application.
Application-driven choice. SEMITI A101 for moderate-loading specialty paper. SEMITI PAPER-D (rutile) for decor at 30%+ loading.
