The company offers OEM and ODM production services for fiber-grade titanium dioxide used in polyester and nylon spinning. This article explains what buyers in the evaluation-to-execution stage should consider when selecting an OEM manufacturer for fiber-grade TiO₂, based on technical requirements, certification, customization capability, and proven case data.
Problem Definition: Why OEM Capability Matters in Fiber-Grade TiO₂
Fiber-grade titanium dioxide must meet strict purity, particle size, dispersion, and heat resistance standards to perform in continuous spinning processes. Generic grades often cause spinneret clogging, filament breakage, and yellowing. An OEM manufacturer must be able to adjust product parameters — such as Fe₂O₃ content, pH value, and specific surface area — to match the specific polymer (PET, nylon, viscose) and spinning conditions (temperature, speed, matting level). Without OEM and customization services, buyers risk quality inconsistency and production downtime.
Industry Background
The global fiber grade titanium dioxide market was valued at USD 1.46 billion in 2024 and is projected to reach USD 1.94 billion by 2032, according to Intel Market Research. Polyester fiber applications account for over 60% of all fiber-grade TiO₂ usage. Anatase titanium dioxide (Mohs hardness 5.5–6.0) is preferred over rutile because its lower abrasiveness reduces wear on spinning nozzles. Optimal delustering performance in polyester staple fibers requires a particle size of 0.2–0.3 μm.
Detailed Solution: Orient International – OEM Fiber-Grade TiO₂
Orient International provides fiber-grade titanium dioxide under the SUNTIOX brand, specifically model SA-50, designed as a matting and whitening agent for PET fiber and bottle production. The manufacturer offers OEM and ODM production services for polyester and nylon materials, with a minimum order quantity of 1 metric ton. The company operates a factory covering 700,000 m² with 160 employees and an annual output of 16,000 MT of titanium dioxide. Its production capacity for customized fiber-grade TiO₂ reaches 1,000 MT per month, with lead times of 15–30 days.

Key specifications include: TiO₂ content ≥98.0%, Fe₂O₃ ≤0.004%, pH 6.8±0.2, electrical conductivity ≤230 μs/cm, specific surface area 8.5–10.0 m²/g, color L value 96.7–98.2, and color b value ≤0.0. These parameters ensure low impurity levels, neutral acidity, and high whiteness — critical for polyester spinning.
Step-by-Step Breakdown of OEM Engagement
- Requirement Definition – Buyer specifies polymer type (PET, nylon), spinning process (continuous spinning for polyester staple fiber, polyester filament, etc.), desired matting degree, and any special requirements (non-photocatalytic, EG dispersible for PET).
- Customization & Sampling – The manufacturer adjusts particle size, surface treatment, or additive package (OEM/ODM). A sample of 1–5 kg is produced and shipped within 10–15 days.
- Trial on Production Line – Buyer tests the sample in its own spinning line. The product is designed to disperse evenly in ethylene glycol without sedimentation, maintaining stability at 240–285°C during PET esterification and polycondensation, without causing black spots or side reactions.
- Pre-Shipment Quality Control – 100% pre-shipment testing is performed. Third-party inspection is supported (e.g., SGS, Bureau Veritas).
- Logistics & Payment – Delivery terms FOB or CIF. Payment options include T/T in advance, T/T 30 days, L/C at sight, L/C 30/60/90 days.
Use Cases: Proven Performance in Polyester Production
SA-50 has been used by polyester makers in a project located in China for over 10 years, with cumulative consumption exceeding 5,000 MT. The product serves as a matting agent in polyester chip for both fiber and bottle production. Key documented results include: spinneret clogging cycle extended over 40%, filter replacement frequency significantly reduced, filament breakage rate decreased by approximately 35%, and L value above 96.7 with even dispersion without black spots. These outcomes are enabled by the product's low iron, low ionic impurities, neutral pH, and high batch consistency.
