SA-50 Titanium Dioxide for PET Fiber Whitening
SA-50 is a premium anatase titanium dioxide designed for PET fiber whitening and matting. With TiO₂ content ≥98.0%, ultra-low impurities, and controlled particle size, it significantly reduces filament breakage by ~35% and extends spinneret service life. The product ensures uniform matte appearance without bright spots, consistent dyeing, and stable high whiteness (L-value 96.7–98.2). Backed by ISO9001 certification and over 30 years of expertise from Orient International.
Key Selling Points
- Reduced Filament Breakage: Mild anatase particles and excellent dispersion lower spinneret abrasion, cutting breakage rate by ~35% and enabling long continuous high-speed spinning.
- Extended Equipment Life: Spinneret clogging cycle extended over 40%, filter replacement frequency greatly reduced, lowering maintenance costs.
- Uniform Matting & Dyeing: Stable adjustable matting degree delivers consistent luster without bright spots; firm particle adhesion prevents powder falling off during weaving and dyeing, with no color streaks.
- High & Stable Whiteness: Color value L ≥96.7 (typical 96.7–98.2) and b ≤0.0 ensure bright white fibers with outstanding anti-yellowing performance.
- Heat & Weather Resistance: Treated particles maintain performance under high-temperature spinning conditions, supporting production of durable fibers.
