Detailed English Translation (Optimized for International Trade)

1. Coatings Industry

   As the largest application sector of titanium dioxide, it accounts for approximately 45% of total consumption. Widely used in interior/exterior architectural paints, automotive topcoats, and industrial anti-corrosive paints, it not only provides exceptional hiding power through its high refractive index (achieving excellent coverage with a small amount of coating) but also absorbs ultraviolet (UV) rays to slow down coating aging, prevent fading and cracking, and enhance color saturation, mechanical strength, and adhesion of the paint film.
2. Plastics Industry

   As the second-largest application sector, titanium dioxide serves multiple purposes in plastic products:

• Improves the appearance and color of white household appliance casings (e.g., refrigerators, air conditioners) and food packaging (e.g., plastic bottles).

• Enhances light resistance, weather resistance, and heat resistance of outdoor plastic products (e.g., pipes, gardening tools), reducing aging and deformation caused by high temperatures and UV radiation.

• Increases the rigidity and impact resistance of plastics when added in appropriate amounts, making industrial components more durable.

3. Papermaking Industry

   Titanium dioxide is mainly used as a filler and coating pigment in the production of high-grade and thin paper. Its addition significantly improves paper whiteness and opacity, preventing ink penetration during writing and printing. It also fills pores on the paper surface, making it smoother and enhancing the uniform absorption of ink during printing.

• Anatase titanium dioxide (without surface treatment) is commonly used in ordinary paper.

• Surface-treated rutile titanium dioxide is required for laminated paper with high light and heat resistance requirements.

4. Cosmetics & Daily Chemicals

   Due to its non-toxicity and high safety, titanium dioxide is widely used in this sector:

• Provides good hiding power in loose powders and foundations, creating a smooth and fair complexion while reducing the greasiness of skincare products.

• Acts as a core physical UV filter in sunscreens, scattering UV rays to protect the skin.

• Enhances the whiteness of white soaps, toothpaste, and other daily necessities.

5. Ink Industry

   An indispensable white pigment in high-grade inks, both rutile and anatase titanium dioxide are used:

• Imparts bright and pure colors to inks; adjusts color saturation in color inks, making printed colors more vivid.

• Prevents ink agglomeration and sedimentation during storage, ensuring smooth printing performance.

• Improves the light resistance of printed products, keeping outdoor billboards and other materials fade-resistant for a long time.

6. Rubber Industry

   Titanium dioxide functions as a colorant, reinforcing agent, and anti-aging agent:

• Provides a pure white color to white rubber soles and medical rubber products.

• Enhances the wear resistance and weather resistance of automotive tires, rubber shoes, and other products, preventing cracking and discoloration under sunlight.

• Anatase titanium dioxide is mainly used, while rutile titanium dioxide is blended in tire production to improve ozone and UV resistance.

7. Other Specialized Fields

• Chemical Fiber Industry: Used primarily as a matting agent. Added to chemical fibers, it scatters light to reduce excessive luster, creating a softer and more natural appearance. It also increases friction between fibers, improving fabric hand feel.

• Food Industry: As a compliant white food additive, it is used in the production of flour, candies, and other foods to enhance brightness and whiteness.

• New Energy & Environmental Protection: Ferrous sulfate (a byproduct of titanium dioxide production) can be used to manufacture lithium iron phosphate, a raw material for power batteries. Additionally, its photocatalytic properties enable the decomposition of organic pollutants, making it suitable for environmental protection coatings and air purification materials.

Translation Notes for International Trade

1. Term Consistency: Core terms (e.g., rutile/anatase titanium dioxide, hiding power, weather resistance) adopt industry-standard English expressions for accuracy in technical documents and quotations.

2. Scenario Adaptation: Emphasizes application-specific performance (e.g., "FDA-compliant" implied in food/cosmetics, "UV resistance" for outdoor products) to meet overseas customer needs.

3. Sentence Structure: Uses concise passive voice and logical connectors (e.g., "additionally," "while") to align with English technical writing conventions, facilitating use in product catalogs and technical specifications.
