卓越的光学性能
DW-1070 features exceptionally high tinting strength and opacity. 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 — ideal for premium white plastic products.
01
Undertone (a vs b)
Lower b → bluer undertone (preferred). a closer to 0 → more neutral. DW-1070 sits bluer and more neutral than the reference.

Brightness
Higher L → brighter / whiter appearance. DW-1070 measures 88.70 vs the reference 88.63.

Brightness × Undertone Map
A combined view of brightness and undertone. The upper-left region — brighter L and bluer b — is the most desirable position for premium white PVC. DW-1070 lands in that target zone.
