Rubber compounder procurement
TiO2 for Rubber Compound Manufacturers
Rubber compounding favors anatase (SEMITI A200) — soft crystal protects Banbury equipment from wear.
Typical volume
100–1500 t/year
Qualification cycle
4–8 weeks
Business context
Rubber compounders supply tire, automotive trim, conveyor belt, and consumer rubber goods industries. White compounds use TiO2 + ZnO + antioxidant system.
Procurement challenges
- 01Banbury rotor / die wear minimization (soft crystal preferred)
- 02Sulfur vulcanization compatibility
- 03Curing acceleration / retardation
- 04Food-grade conveyor belt compliance
What SEMITI brings
SEMITI A200 anatase for general rubber compounding. SEMITI A100 for fiber delustering and rubber. FDA-compliant for food-grade conveyor.
Recommended SEMITI grades for rubber compound manufacturers
SEMITI A200
anatase · sulfate
Rubber & Fiber Anatase
Anatase for white tire sidewall, EPDM, synthetic fiber delustering — soft crystal, low equipment wear.
SEMITI A100
anatase · sulfate
Universal Anatase
Universal anatase grade for inks, paper, fiber and rubber — bright white with soft, easily-dispersed crystal.

Common questions
Why anatase for tire sidewall instead of rutile?+
Anatase (Mohs 5.5-6) is softer than rutile (6-6.5) — significantly less Banbury rotor wear. Tire sidewall service life matches tire life (~5 years), so anatase's UV durability gap isn't a service issue.
