Rutile Titanium Dioxide R350 CAS 13463-67-7 Paper Grade for Decorative Paper
Rutile Titanium Dioxide R350 is dedicated paper‑grade rutile titanium dioxide for decorative paper industry. With alumina‑silica composite surface treatment and strict particle‑size control, it delivers outstanding opacity and brilliant whiteness. It owns good retention performance in paper pulp system, disperses evenly during pulping and papermaking process. It effectively improves covering power, brightness and surface smoothness of decorative paper. It has good compatibility with pulp, sizing
Product Overview
Rutile Titanium Dioxide R350 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide optimized for decorative papermaking. Fine particle classification matches the requirement of decorative paper filler. Composite surface modification enhances pulp wettability and retention rate. This grade solves common pain points including insufficient paper opacity, poor brightness, uneven color and low pigment retention. Reliable quality adapts to wet‑end adding process for large‑scale decorative paper production.
Key Features
- High opacity and superior whiteness, significantly improve covering power and brightness of decorative paper.
- Good pulp retention performance, reduce pigment loss and lower production cost.
- Excellent dispersion in pulp system, avoid speckle defects and guarantee uniform paper sheet tone.
- Improve surface smoothness and printing adaptability of finished decorative paper.
- Good compatibility with plant fiber, sizing agent, wet‑strength agent and other papermaking auxiliaries.
- Stable chemical property, no negative impact on paper forming and post‑processing performance.
