Rutile TiO2 R340 is paper‑special rutile titanium dioxide designed for laminated paper and paperboard. With composite inorganic‑organic surface modification and strict particle classification, it provides outstanding opacity and bright whiteness. It keeps stable performance under hot pressing and laminating conditions, maintains high retention rate in pulp system, disperses evenly to avoid surface speckles. It improves covering power, surface smoothness and visual appearance of laminated paper a

Product Detail

Product Overview

Rutile TiO2 R340 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide optimized for laminated paper and paperboard applications. Controlled particle‑size distribution delivers high hiding power. Composite surface treatment enhances wettability and retention in aqueous pulp. This grade solves common pain points such as insufficient opacity after hot lamination, color fading, low retention and uneven paper surface. Consistent product quality adapts to large‑scale wet‑end feeding for laminated base paper and various paperboard production.

Key Features

High opacity and whiteness, enhance covering effect and visual performance of laminated paper and paperboard.
Excellent thermal stability, resist discoloration under high‑temperature hot‑press laminating process.
Good retention performance in pulp, reduce pigment loss and lower comprehensive production cost.
Uniform dispersion in pulp system, decrease speckle defects and guarantee consistent sheet tone.
Improve surface smoothness of finished paper, promote lamination bonding effect.
Good compatibility with papermaking fiber, wet‑strength agent, retention aid and sizing chemicals.

Main Applications

‑ Furniture decorative laminated base paper

‑ Melamine laminated paper

‑ Packaging paperboard and heavy‑duty cardboard

‑ Industrial laminated composite paper

‑ Other paper and paperboard requiring high whiteness and thermal resistance for lamination

Usage Recommendation

‑ Recommended dosage: 3‑11 wt% based on dry pulp weight, adjust by opacity and whiteness requirements.

‑ Pre‑prepare well‑dispersed titanium dioxide slurry before adding into pulp tank.

‑ Use matching retention aid to raise pigment retention rate.

‑ Keep pulp pH in normal papermaking range.

‑ Run small‑scale papermaking and hot‑press lamination trial test before mass 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.

‑ Shelf life: 24 months under standard storage conditions.
