Introducing DongFang TiO₂ for Papermaking R5567 Rutile Titanium Dioxide

Built for Papermakers, Designed by Chemists

Working as both chemists and paper-industry partners, we understand how critical titanium dioxide is for papermaking. We developed DongFang TiO₂ R5567 to deliver high opacity and clean brightness, especially for coated and specialty paper producers who face demands for performance and cost balance daily. While titanium dioxide is a well-known pigment, not all grades perform with the consistency or durability modern paper mills need. Our R5567 takes into account real-world conditions we see inside mills, not just laboratory theory.

Performance Where It Counts—Brightness, Opacity, Dispersion

Years of operating reactors and refining precipitation steps taught us that brightness alone does not tell the whole story. Customers bring us problems: yellowing in recycled paper, patchy coverage in fast-running coaters, difficulty in dispersing pigment into certain binder systems. The rutile form in R5567 is stabilized through a robust surface treatment that resists yellowing during shelf-life or reprocessing. You get a whiteness in the finished sheet that holds up under the ultraviolet light of office scanners and lamps, and that stands out on the newsstand or in print catalogs.

Our mills achieve paper opacities that prevent print show-through, which downstream printers appreciate. We see the real impact of opacity on issues like double-sided print registration and color fidelity, especially for lightweight publishing grades. We target particle morphology and surface treatment to keep R5567 dispersible in both alkaline and neutral papermaking systems, even at high solids loadings. That means less downtime babysitting pigment pumps or battling flocculation in the blender. It saves on dispersant usage and reduces variation in brightness across the roll.

Consistency and Value, Sheet After Sheet

Market pressures squeeze both suppliers and mills, with both sides feeling the bite of price volatility. We control every step of production—ore selection, chlorination, oxidation, wet treatment, drying, and micronization. In practice, this keeps particle size within a range that optimizes hiding power without sacrificing runnability. Factory teams test each lot with tools that match mill laboratory procedures, not just basic QC protocols. This narrows the gap between specification and mill experience. We avoid the wild swings in rheology and particle agglomeration that show up in cheaper alternatives.

Large-volume contracts with several coated and uncoated graphical paper plants give us a chance to study real output. Operators regularly remark on less clogging in filters and screens. Our technical staff works directly with mill chemists to troubleshoot slurries and optimize the dosages for best sheet properties without excess waste. In one project with a packaging board producer, the plant cut pigment consumption by 5% by fine-tuning the R5567 dose, while maintaining sheet brightness and opacity. These kinds of results grow from hands-on work and direct accountability.

Why Rutile R5567 Outperforms Standard Grades

Several competing products claim to perform across all paper grades, but in reality, many grades marketed by traders are optimized for general paint or plastics use, not paper. The process details make a difference. We adjust crystal growth during calcination and tightly control milling parameters to minimize oversize particles. This sharply reduces defects like streaks and specks on the final sheet surface. The rutile structure of R5567 gives it greater photostability compared to anatase grades, and the silica/alumina coating guards against photo-induced degradation. Paper mills using R5567 report reduced yellowing during storage, even in geographies with strong sunlight.

Our manufacturing experience has shown us that most titanium dioxide grades being relabeled for paper often lack dispersion stability. R5567 is engineered for rapid, even dispersion under the sheer rates found in modern papermaking equipment. In head-to-head mill trials, our pigment delivered smoother profiles on optical scanners and lower additive demand for retention. In the practical world of mill scheduling, that means fewer process upsets and easier grade changes, especially when switching between recycled and virgin stock.

Trusted by the Paper Industry: From High-Speed Coaters to Packaging Lines

Feedback from plant trials shapes our approach more than any laboratory data sheet. In mills where downtime costs stack up quickly, the runnability of a pigment becomes just as important as its paper performance. R5567’s robust hydrophilic surface treatment means less settling during storage and transit. No surprise clumping or flow problems when the concentrate hits the system. Operators in several Asian and European mills tell us they can use R5567 directly in-line without extra dispersion steps—a direct result of the product’s careful wet treatment and strict particle control.

Packaging producers find particular value in R5567 for board applications where ink absorption and surface smoothness matter. One carton plant using recycled fiber saw print quality improve after switching to this grade, thanks to more even pigment distribution and a reduction in coating defects. High brightness in specialty paper helps printers achieve vibrant colors without excessive ink consumption, which translates to cost savings both upstream and downstream.

Delivering Environmental and Economic Benefits

Environmental standards in papermaking continue to tighten. We have kept R5567’s process free from harmful residues that complicate downstream effluent treatment. Lower dispersant and retention aid usage translates to cleaner white water loops and lower COD loads at the effluent plant. In high-volume mills, even small gains in process cleanliness mean measurable reductions in chemical usage and downstream filtration requirements. Operators confirm lower foam and less build-up in clarifiers while running R5567, which cuts overall operational costs.

R5567 delivers high efficiency at lower doses, supporting better raw material utilization and reduced freight costs per ton of finished paper. Its stable color index helps plants manage batch-to-batch variability, minimizing waste of off-spec sheets. Tournament runs in multilayer board systems show stronger at-line color consistency, which helps converters and printers minimize waste in finishing and converting operations.

Safety in Handling and Day-to-Day Operations

Our factory personnel and downstream users handle bulk titanium dioxide daily; we know the realities of powder management. R5567’s controlled grind ensures minimal dustiness and keeps filter changes on respirators low, supporting safer working environments. Consistent moisture control makes pneumatic transfer and storage straightforward, whether delivered as dry powder or pre-dispersed slurry. No surprises—just reliable flow and ease of integration. Several end-users commented during technical audits that our pigment handled cleaner and safer than other brands, cutting down time spent on housekeeping and maintenance.

Why Experience and Vertical Integration Matter

Years of direct technical support in papermaking plants taught us which traits block productivity and which unlock more value from everyday operations. We have adjusted our calcination and surface treatment recipes based on feedback from real-life mill headaches—settling in tanks, rapid pH swings, pigment plate-out in sensitive headboxes. Our process engineers and field teams bring lessons learned from decades across different paper systems, from lightweight newsprint to triple-coated art papers.

We do not source intermediates from multiple outside providers; we own each step from ore to packed shipment. This keeps contamination in check and keeps surface chemistries predictable. Our partners in the field benefit from product support that does not defer to third-party labs or generic technical bulletins. Mill teams receive real troubleshooting, based in process chemistry, not sales talk. In a decade of supplying R5567, customers have relied on us to resolve process upsets and help lower formulation costs—backed by our firsthand knowledge of both pigment chemistry and full-scale manufacturing.

How R5567 Stands Apart from Standard Rutile and Anatase Grades

Regular anatase titanium dioxide delivers high initial brightness, but lacks the lightfastness or hiding power needed for offset and digital print papers. Standard rutile grades not developed for papermaking often underperform in dispersion and compatibility, especially in pH ranges commonly found in recycled and specialty papermaking. We have seen pigment residues causing specking and uneven sheet formation, leading to costly clean-ups and yield loss. R5567’s surface treatment resists these challenges, delivering reliable results roll after roll, run after run.

Many pigment producers offer a one-size-fits-all titanium dioxide. Our experience shows paper producers need more. R5567 brings better brightness retention and predictable runnability, delivering stronger opacity in both single-pass and multilayer coating systems. In rigorous print and optical testing, our pigment maintains whiteness longer, even under high-light environments or after extended storage. Papermakers running R5567 can confidently push process speeds without running into the limits of what the pigment can handle.

Partnership Grown from Hands-On Experience, Not Just Samples

We believe real progress comes from listening to mill engineers, monitoring machine operation, and helping fine-tune pigment use on the factory floor. In the drive for lower energy and raw material costs, R5567 has helped customers achieve lower base weights and brighter end-products without boosting filler load or sacrificing sheet strength. We track feedback from start-up trials to full production cycles, building the tweaks we see first-hand into our next batches.

Every plant, every line runs a little differently. Our teams visit mills to review process steps, test pigment fit, and advise on seasonal changes—humidity, temperature, stock variability. That’s how we help customers get the most out of each kilogram. We do not rely on generic protocols, but applied experience and continuous feedback—closing the loop between lab, factory, and customer plant.

Commitment to Quality—From Sourcing to Shipping

Pigment quality depends on more than the last QC test. It comes from thoughtful sourcing and strict process discipline at every stage. R5567 is produced using high-purity feedstock, with no recycled or reclaimed raw material that could introduce unwanted metals or organic residues into the paper stream. We run our calcination and surface treatment lines to tight temperature and residence-time profiles, eliminating off-color and unstable by-products. Packaging is designed to handle real mill conditions: bulk bags built for safe handling, lined for moisture control, and verified for shipping stability.

Smart Support Makes All the Difference

Our technical teams do not stop at shipment. Papermaking is a live process, and unexpected things happen in production—changes in fiber mix, pH swings, rapid-run settings, tiny shifts in coat weight or base paper. We offer ongoing support that includes pigment application advice, monitoring of mill performance, and diagnostic checks when problems arise. Customers share concerns—they trust us to offer workable answers rooted in manufacturing and process chemistry. In an industry where a minor pigment hiccup can shut down a four-meter-wide machine, we stand alongside our partners for the long run.
