SEMITI A200
Anatase for white tire sidewall, EPDM, synthetic fiber delustering — soft crystal, low equipment wear.
SEMITI A200 is a sulfate-process anatase tuned for rubber and synthetic fiber applications — white tire sidewalls, EPDM weather strips, conveyor belts with white compounds, and PET/PA/PP fiber delustering. The grade is supplied with minimal inorganic surface treatment, optimized for compatibility with rubber and polymer-melt processing.
For tire makers and rubber compounders, the soft crystal hardness of anatase is the key advantage — it doesn't wear extruder screws and dies the way rutile does at the high mechanical shear of rubber compounding. For synthetic fiber producers, the fine particle size and clean melt-rheology of SEMITI A200 enables consistent delustering at 0.3–0.5% loading without breaking fibers at high draw ratios.
Why customers pick SEMITI A200
- 01Soft crystal — 60–70% less equipment wear than rutile in rubber compounding
- 02Fiber-grade purity — low metallic content prevents spinneret deposits
- 03Clean melt rheology for high-draw fiber spinning

| Crystal hardness (Mohs) | 5.5–6.0 (vs rutile 6.0–6.5) |
Typical dosage
Starting points for formulator trials — final loadings should be optimized in-house.
vs international reference grades
Comparisons against the international grades most commonly cross-referenced by formulators.
SEMITI A100 is universal; A200 is rubber and fiber-specific. For tire and fiber applications choose A200 for better processing characteristics.
TIPAQUE A-100 is the global reference for fiber and rubber anatase. SEMITI A200 is the direct alternative — same crystal characteristics, lower delivered cost.
Packaging & shipping
25 kg paper bag with PE liner; 500 / 1000 kg FIBC. Keep sealed and dry — anatase is moisture-sensitive over long storage. Consume within 12 months.
