SA-50 Titanium Dioxide for PET Chip Production
SA-50 is a high-performance anatase titanium dioxide specifically engineered for PET chip production. With TiO₂ content ≥98.0%, low iron (Fe₂O₃ ≤0.004%), and neutral pH (6.8±0.2), it ensures excellent dispersion in ethylene glycol and stable performance during polymerization. The product delivers even matting without black spots or crystal points, maintaining PET chip intrinsic viscosity and enabling consistent production. Certified ISO9001 (TUV SUD) and backed by 16,000 MT annual capacity from a state-owned supplier founded in 1988.
Key Selling Points
- Ultra-Low Impurities: Fe₂O₃ ≤0.004% and electrical conductivity ≤230 μs/cm minimize side reactions, preserving PET chip intrinsic viscosity and melt fluidity.
- Stable High Whiteness: Color value L ≥96.7 (typical 96.7–98.2) with b ≤0.0, ensuring bright, uniform matte finish without yellowing.
- Excellent Dispersion: Sieve residue (325 mesh) ≤0.004% and specific surface area 8.5–10.0 m²/g enable homogeneous distribution in ethylene glycol, preventing sedimentation and agglomeration.
- Process Compatibility: Neutral pH and hydrolysis resistance allow direct use in 240–285°C PET esterification and polycondensation without process modification.
- Proven Performance: Used by major Chinese polyester makers (Hengli, Tongkun, Rongsheng, Xinfengming) for over 10 years, with consistent results.
