product description

PRODUCT DESCRIPTION

Titanium dioxide (TiO₂) is a high-purity inorganic pigment and opacifier for PVC formulations, delivering exceptional whiteness, brightness, and opacity. The rutile grade offers superior weather resistance and UV stability, making it ideal for outdoor PVC products. It disperses uniformly in PVC melts, ensuring consistent coloration and hiding power while enhancing the mechanical properties of finished products.
