01
Optical Performance
DW-1070 is a super-dispersed TiO2 masterbatch engineered for plastic applications. Benchmarked against the rutile reference sample TiO2(616S), DW-1070 delivers higher brightness (L), a cleaner bluer undertone (b), and a more neutral a-coordinate — a combination that is highly desirable for white plastic products requiring premium aesthetics.

Weather Resistance
Accelerated weathering simulates outdoor UV exposure for PVC window and door profiles. Test specimens were dosed at 3% pigment loading — one using the reference rutile TiO2(616S) and one using DW-1070 — then tracked for ΔE color shift across 168 hours of UV exposure under ISO 4892-3. Throughout the full test, DW-1070 tracked at or slightly below the reference, ending at ΔE 1.19 vs 1.22 — confirming that DW-1070 delivers weather resistance equal to or better than a premium rutile reference.

Opacity Strength
Opacity is calculated as 100 × (1 − transmittance). Under identical loading, DW-1070 matches the reference rutile TiO2(616S) at 6.0% transmittance and 94% opacity — confirming that the super-dispersed masterbatch delivers equivalent hiding power while providing the dispersion and processing benefits described in later sections.

Thermogravimetric Analysis (TGA)
Low volatile content is critical for high-temperature plastics processing — excess moisture or volatiles cause bubbles, silver streaks and surface defects. DW-1070 retains 99.5% of its initial mass even at 150 °C, confirming an ultra-low volatile content suitable for demanding extrusion and injection-molding conditions.

Improving Compounding Efficiency
Incorporating DW-1070 significantly reduces the time required to reach a homogeneous melt state, effortlessly shortening processing cycle times. This not only translates to higher production efficiency but also drives down unit energy consumption and overall manufacturing costs.
