Titanium Dioxide A1 is economical anatase titanium dioxide specially developed for papermaking industry. Adopting sulfate process with controlled particle‑size distribution, the product delivers high whiteness and outstanding opacity. It disperses easily in aqueous medium, suitable for wet‑end filling and paper coating color formula. It can effectively improve paper brightness, opacity and printing performance, reduce print‑through defect. It shows good compatibility with plant fiber, coating bi

Product Detail

Product Overview

Titanium Dioxide A1 CAS 13463‑67‑7 is sulfate‑produced anatase titanium dioxide dedicated to paper filler and coating color. Optimized particle size balances whiteness, opacity and slurry dispersibility. This grade solves common papermaking problems including insufficient opacity, low retention, poor slurry stability and uneven coating surface. It adapts to wet‑end feeding and coating color mixing production process for mass paper manufacturing.

Key Features

High whiteness and excellent hiding power, significantly boost paper opacity and restrain show‑through print‑through.
Good water dispersibility, easy to prepare stable paper‑making slurry and coating color.
Reasonable particle property, obtain ideal retention rate in pulp system, cut pigment consumption cost.
Promote paper surface smoothness and ink absorption, upgrade finished paper printing effect.
Excellent compatibility with pulp fiber, latex binder, retention agent and other papermaking auxiliaries.
Chemically inert, will not cause discoloration or other side‑effects during paper drying and post‑treatment.

Main Applications

‑ Wet‑end filler for cultural printing paper, copy paper

‑ Coating color pigment for coated paper and art paper

‑ General‑grade decorative base paper

‑ Packaging paper and paperboard with high whiteness requirement

‑ Other paper products requiring inorganic white filler and coating pigment

Usage Recommendation

‑ Recommended dosage: 2‑9 wt% based on dry pulp for wet‑end filling; 4‑16 wt% in coating color formula, adjust according to whiteness and opacity requirements.

‑ Prepare well‑dispersed TiO₂ aqueous slurry before adding to pulp chest or coating tank.

‑ Appropriately match retention aid system to improve pigment retention for wet‑end application.

‑ Control slurry pH within standard papermaking scope.

‑ Run small‑scale papermaking or coating trial before large‑scale production.

Storage & Packaging

‑ Packaging: 25kg moisture‑proof kraft paper bag with PE inner liner.

‑ Storage: Store in dry, cool and ventilated warehouse, keep tightly sealed against moisture absorption and caking.

‑ Shelf life: 24 months under standard storage conditions.
