Papermaking is the third largest user of titanium dioxide after coating and plastic industries.
Titanium dioxide (TiO2) is widely used in the production of high-end paper. Considering the production cost, the low-end paper generally does not use titanium dioxide but uses materials such as talc, calcium carbonate, and calcined kaolin. Compared with these materials, titanium dioxide (TiO2) has a high whiteness, high density, high refractive index, fine and uniform particles, which means that the paper using titanium dioxide has good whiteness and strong hiding power, high strength, thin and smooth and not easy to penetrate during printing. The opacity of the paper using titanium dioxide is about 10 times higher than that of other materials, and the weight can be reduced by 15% to 30%.
Titanium dioxide TiO2 is mainly used in several kinds of paper productions, as below:
Laminated Paper
The decorative paper is commonly used for furniture and flooring, the amount of titanium should be more than 20% to fulfill the requirement such as opacity, gloss retention, color, and adhesion.
Coated Cardboard
The carboard used for packaging purposes such as small boxes. Titanium dioxide is mainly used for the surface coating of this cardboard because of the low brightness. The amount of titanium dioxide should be higher than 20%, as the opacity is a crucial factor to cover the original cardboard.
Bleached Cardboard
This cardboard is commonly used to produce paper cups and folding cardboard boxes (liquid and solid packaging). Titanium dioxide is vital for cardboard coating to deliver a particular brightness and color.
Calendering and Non-Calendering Fibre-Free Paper
This paper is used for letters, business, and photocopying of magazines and advertising purposes high-level paper. The main reasons for using titanium dioxide in this paper making is the requirement of opacity, brightness, adhesion, optical brightness.
Calendered Wood Pulp Paper
This paper is mainly used for samples such as mail orders, inside newspaper paper, and general magazine publications. In the coating of these products, titanium dioxide plays an important role in improving the opacity and brightness characteristic.
G&J Resources provides grades in powder form for a broad range of paper and paper coatings applications. we offer products such as a tailor-made rutile grade for paper laminates which shows outstanding UV stability and highest yellowing resistance.
NR-956 is a highly coated sulfate grade with superior brightness a warm tone for applications, such as paper and cardboard coatings, lightweight coated paper (LWC paper), matt emulsion paints and lamination printing inks. NR-956 significantly improves the wet and dry opacity of paper and cardboard.
NA-100 is an untreated anatase pigment for use in paper pulp, glazes, and rubber. It imparts high brightness, which can be further improved in combination with optical brighteners and has a neutral tone. It provides high wet and dry opacity in paper applications.
TYR-588 is a chloride pigment designed for decor papers and foils. It disperses readily and displays excellent opacity and retention performance, making it very economical in use. TYR-588 exhibits very high reflectance with a bluish tone in white paper laminates as well as superior UV-graying stability and excellent yellowing resistance.
