Core application areas of titanium dioxide

Titanium dioxide, with its three major advantages of high whiteness, coverage, and weather resistance, has penetrated into multiple fields of the national economy. The specific application and selection logic are as follows:

1. Coating industry (accounting for about 60%)

Architectural coatings: For exterior wall paint, a strong weather resistant rutile type (such as R2310 chloride method) is required, while for interior wall paint, an anatase type can be selected to reduce costs.

Automotive coatings: Car topcoats require extreme weather resistance and gloss, and require specialized chlorinated gold and red stone type (such as Komu R706); Mid to low end commercial vehicles can choose domestically produced sulfuric acid method pyrite type.

Special coatings: Powder coatings (for household appliance casings) and anti-corrosion coatings (for ships and bridges) both rely on the acid and alkali resistance of rutile type.

2. Plastic industry (accounting for about 20%)

Function: Improve the light resistance of plastic products (preventing aging and fading), covering power (such as white PVC pipes), and reduce costs (reducing resin usage).

Typical case: Longbai Group's "Xuelian Brand" chlorinated titanium dioxide BLR-885 significantly improves the UV aging resistance of PVC products through surface silicon oxide coating technology, making it suitable for outdoor plastic building materials.

3. Paper industry (accounting for about 14%)

Application scenarios: Decorative paper (furniture veneer), Bible paper (thin printing paper), currency paper, etc., need to be selected according to whiteness and weather resistance:

Sharp titanium type: used for low ash paper (such as Bible paper), providing high whiteness and low cost;

Rutile type: used for high ash decorative paper to ensure that the printed pattern does not penetrate and is resistant to yellowing for a long time.

4. High end emerging fields

MLCC ceramic capacitors: Electronic grade titanium dioxide is used as a raw material for barium titanate in 5G base stations and new energy vehicles (with a single MLCC usage of over 10000 pieces). Domestic companies are breaking through the technological monopoly of Japan's Ishihara (ISK).

Cosmetics: Nano sized rutile titanium dioxide (such as particle size 5-10nm) is used as a physical sunscreen, with both transparency and UV shielding ability (SPF value increased by more than 30%).
