Rutile Titanium Dioxide R818
Jinan Yuxing R818: general-purpose sulphate-process rutile titanium dioxide with a yellow undertone. Review TDS limits, applications and sample qualification.
R818 is a general-purpose Jinan Yuxing rutile grade with a yellow undertone.
The manufacturer TDS lists plastics, coatings, rubber, masterbatch and papermaking. It specifies TiO2 purity of at least 94%, Si/Al inorganic coating plus organic treatment, oil absorption no more than 22 g/100 g and pH 6.5-8.5. These are specification limits, not batch results.
R818 manufacturer TDS data.
These values are specification limits from the supplied Jinan Yuxing TDS, not batch results. The current controlled TDS, agreed sales specification and lot COA govern acceptance.
| Parameter | Manufacturer specification | Buyer action |
|---|---|---|
| TiO2 content | >=94% | Confirm the controlled TDS and agreed test method. |
| Rutile conversion | >=98.0% | Retain in the purchasing specification if crystal conversion is an acceptance item. |
| 105 C volatile matter | <=0.8% | For plastics, consider a buyer-specific moisture or volatile requirement. |
| Water-soluble matter / hydrotrope (TDS wording) | <=0.5% | Confirm the controlled TDS wording and analytical method. |
| Sieve residue, 45 micrometres | <=0.05% | Pair with the buyer's dispersion or fineness-of-grind test. |
| Tinting strength vs standard | >=112% | Do not compare directly with R838 Reynolds-number data. |
| pH, aqueous suspension | 6.5-8.5 | Check compatibility with the resin, binder and additives. |
| Oil absorption | <=22 g/100 g | Evaluate viscosity and dispersant demand in the actual formulation. |
| Water-extract resistivity | >=50 ohm m | Confirm units and method on the current TDS. |
| Average particle diameter | 0.22-0.28 micrometres | Use as a TDS descriptor; application dispersion still requires a trial. |
| CIE L value | >=98 | Confirm the colour method and reference standard. |
| Dispersibility | <=20 micrometres | Verify with the buyer's process and quality method. |

Where R818 is a documented starting grade.
Manufacturer-listed applications define the starting scope. Final suitability depends on the buyer's formulation, process and acceptance tests.
R818 or R838?
R818 has a yellow undertone and general-purpose positioning. R838 has a blue undertone and is particularly suited to waterborne coatings. These qualitative selection characteristics complement the TDS limits; confirm colour and performance in the actual formulation.
Plastics and masterbatch
Both are listed in the manufacturer TDS. Validate dispersion, moisture or volatiles, processing stability, filter pressure and finished-part colour against the incumbent.
Coatings
Coatings are listed as a universal application. The TDS does not make a specific exterior-weathering claim, so approve gloss, hiding, viscosity and durability in the buyer's formulation.
Rubber
Rubber is explicitly listed. Confirm dispersion, colour and any process-specific heat or cure compatibility during the trial.
Papermaking
Papermaking is explicitly listed. Evaluate opacity, brightness, retention and process behaviour against the approved reference.
R818 buyer qualification checklist
- Fix Jinan Yuxing R818 as the named producer and grade on the RFQ.
- Approve the current controlled TDS and SDS before commercial use.
- Define the lot COA limits and any buyer-specific application test.
- Run a controlled comparison against the incumbent in the actual formulation.
- Confirm packaging, pallet, container loading, destination documents and Incoterm.

R818 sourcing questions.
Who manufactures R818 titanium dioxide?
Jinan Yuxing Chemical manufactures the R818 presented on this site. TiO2 Source coordinates product information and inquiries; the contractual seller and exporter are confirmed for each transaction.
What applications are listed for R818?
The manufacturer TDS lists plastics, coatings, rubber, masterbatch and papermaking. Final suitability must be confirmed in the buyer's formulation and trial protocol.
Is R818 specifically guaranteed for exterior coatings?
No specific exterior-weathering guarantee appears in the supplied TDS. Treat R818 as a universal listed coatings grade and qualify durability against the required warranty and exposure target.
Can I obtain the current R818 TDS and a batch COA?
The current controlled TDS is available with a quotation. Each commercial lot ships with a COA against the agreed specification; the source PDF is not offered as a public download on this site.
Can R818 replace another rutile grade directly?
Not without a trial. Compare producer, treatment, test methods and COA limits, then test dispersion, colour, hiding, viscosity or processing in the actual system.
