SR-240 Rutile Titanium Dioxide with ≥96.0% TiO₂ Content, ≥97.0% Rutile Content, and ≥185% Tint Reducing Power

SR-240 Rutile Titanium Dioxide – Technical Product Report

1. Executive Summary

SR-240 is presented in the supplied technical data sheet as a rutile titanium dioxide (TiO₂) pigment designed to provide excellent gloss, hiding power, non-chalking behavior and good dispersion in plastics and rubber. The product is described as having an aluminum-based inorganic surface coating together with an organic treatment.

The stated specifications include TiO₂ content of ≥96%, rutile content of ≥97%, whiteness of ≥97%, an L value of ≥98 and tint reducing power of ≥185%. These properties position SR-240 as a high-performance white pigment candidate for masterbatch, plastics, rubber and flexible PVC applications.

The source sheet also introduces SR-240+ as an upgraded version with higher bulk density. It states that SR-240+ can produce higher-concentration masterbatch without adding a separate dispersing agent. This report treats SR-240 as the primary product and discusses SR-240+ only as the upgrade positioning stated in the source sheet.

2. Product Overview

3. Product Characteristics

The supplied document describes SR-240 as a rutile titanium dioxide pigment with an aluminum-based inorganic surface coating and organic treatment. Surface treatment can influence dispersion, gloss, hiding power, processing behavior and interaction with polymer or rubber matrices.

The data sheet specifically emphasizes excellent gloss and hiding power, non-chalking characteristics and good dispersion in plastics and rubber. These characteristics make SR-240 relevant to applications where white appearance, surface quality and processing efficiency are important.

4. Technical Data

Source note: Values are reproduced or reorganized from the supplied technical data sheet. Confirm them against the current supplier certificate of analysis or test report for contractual use.

5. Technical Performance Interpretation

High rutile content: Rutile content of ≥97% indicates a highly rutile pigment, supporting strong optical performance and durable white pigmentation.

Whiteness and lightness: Whiteness ≥97% and L value ≥98 indicate a bright, high-lightness pigment suitable for white masterbatch, plastics, rubber and flexible PVC.

Tinting strength: Tint reducing power ≥185% indicates strong comparative pigment strength; optimum dosage should be determined in the customer's formulation.

Gloss and hiding power: The source specifically emphasizes excellent gloss and hiding power, supporting clean appearance and efficient white coverage when dispersion is well controlled.

Non-chalking behavior: The stated non-chalking characteristic is relevant where long-term surface appearance and resistance to powdering are important.

Dispersion: Good dispersion in plastics and rubber is a key positioning point; actual performance depends on equipment, shear, temperature, additives, polymer type and pigment loading.

pH and oil absorption: pH 6.5–8.0 indicates a near-neutral material, while oil absorption of 15–18 g/100 g provides a useful formulation reference for binder demand and viscosity.

6. Application Areas

The application list is based on the supplied technical data sheet. Final performance should be validated under the customer's actual formulation and processing conditions.

7. Masterbatch & SR-240+ Upgrade Positioning

The source describes SR-240+ as an upgraded version of SR-240 with higher bulk density. It states that SR-240+ can produce higher-concentration masterbatch without adding a dispersing agent. This may improve loading efficiency and handling, but should be verified on the customer's equipment and formulation.

8. Formulation & Processing Considerations

Use adequate shear and a compatible dispersing/wetting system when required.

Evaluate pigment loading, bulk density, feeder accuracy and melt viscosity for masterbatch production.

For plastics, assess temperature, residence time, shear history and polymer/additive compatibility.

For rubber, evaluate dispersion, viscosity, color, cure behavior and mechanical properties.

For flexible PVC, check compatibility with plasticizers, stabilizers, lubricants and other additives.

Where gloss and hiding are critical, conduct standardized color, gloss, opacity and surface-quality tests.

9. Quality Control & Incoming Inspection

Each commercial lot should be checked against the agreed specification and supplier certificate of analysis.

10. Classification and Standards

For contractual or regulatory documentation, confirm the applicable standard edition, test method and acceptance criteria with current supplier documentation.

11. Packaging

12. Storage, Handling & General Safety

Store in a dry, clean and well-ventilated area. Minimize dust generation and follow the applicable Safety Data Sheet (SDS), workplace exposure controls and local regulations. This report does not replace the official SDS.

13. Commercial & Technical Evaluation Summary

14. Conclusion

Based on the supplied technical data sheet, SR-240 is positioned as a high-performance rutile titanium dioxide pigment with strong optical properties, high rutile content, good dispersion characteristics and a surface-treatment system designed for plastics and rubber applications.

Its combination of whiteness ≥97%, L value ≥98% and tint reducing power ≥185% supports its positioning for high-quality white pigmentation. SR-240 is particularly relevant to masterbatch, plastics, rubber and flexible PVC. Before commercial approval, users should conduct side-by-side trials against their incumbent TiO₂ grade, focusing on color strength, dispersion, gloss, hiding power, processing behavior and final
