Rutile Titanium Dioxide (TiO₂)
Description :
Product Description:
Key Application Points of Rutile Titanium Dioxide in PVC :
Main Functions : Provides high opacity, high brightness, weather resistance (anti-yellowing, anti-degradation), and UV absorption.
Application : PVC pipes, profiles, doors and windows, sheets, cables, and flexible PVC products.
Product Features:
High weather resistance : Absorbs ultraviolet rays, extending the lifespan of plastic products outdoors.
Good dispersibility: Reduces color spots and provides stable color and performance.
Low oil absorption: Ensures good processing fluidity.
Common Grades: Special plastic-grade rutile titanium dioxide (e.g., produced by the sulfate process, with dense surface treatment, and good temperature resistance)
