R218 Titanium Dioxide Color for Plastics, Masterbatch & PVC
When it comes to achieving brilliant whiteness and stable titanium dioxide color in plastics, R218 is a trusted rutile TiO₂ pigment. Manufactured through the sulphate process, R218 is engineered with alumina, silica, and organic surface treatments that make it highly suitable for demanding plastic and polymer applications.
🔹 Advantages of R218 in Plastics
Consistent Titanium Dioxide Color: Ensures high whiteness and clean appearance in finished products.
Excellent Dispersion: Mixes easily in polymer systems, reducing processing time.
High Tinting Strength: Provides stronger coloration and better covering power with lower dosage.
Heat & Light Stability: Maintains brightness under extrusion and outdoor exposure.
Low Oil Absorption: Improves compatibility with plasticizers and polymer formulations.
🏭 Applications of R218 Titanium Dioxide Color
R218 is widely used in the plastics and polymer industry, delivering superior performance in:
PVC Products: Pipes, profiles, sheets, window frames, and films.
Masterbatch & Color Concentrates: Excellent dispersibility for white and colored masterbatches.
Polyolefins (PE & PP): Packaging films, containers, injection-molded parts.
Styrenics (PS, ABS): Household items, electronics casings, toys.
Polyurethane & Rubber: Enhances whiteness and durability in elastomers and foams.
By using R218, manufacturers can achieve stable titanium dioxide color performance across a wide range of plastic applications, from construction materials to consumer goods.
