There are four blue pigment for plastics,and key features are as below.
| S.N. | Product Name | Chemistry | C.I.Index |
| 1 | pigment blue 15 | Cu-Phthaloblue, non-stab | 74160 |
| 2 | pigment blue 15:1 | Cu-Phthaloblue, α-Mod | 74160 |
| 3 | pigment blue 15:3 | Cu-Phthaloblue, β-Mod | 74160 |
| 4 | pigment blue 60 | Indanthrone | 69800 |
Pigment Blue 15:1 is of high tinting strength,pure red shade pigment blue,high light/heat resistance
Pigment Blue 15:3 is of high tinting strength,pure green shade pigment blue,high light/heat resistance
Pigment Blue 15 is of high tinting strength,pure red shade pigment blue,good light/immigration resistance,heat resistance 200℃.due to PB 15 not stable crystal structure and heat resistance goes down
Pigment Blue 60 is of pure red shade pigment blue,good properties, suited for nylon,excellent weather resistance.Redder & better weather resistance than pigment blue 15:1
all these 4 plastic blue pigment technical position as below
Here we use pigment blue 15:1 as the standard blue pigment, commercial production makes it's price acceptable.
Pigment blue 15:3 is β form and stable than pigment blue 15:1, thus,properties is also better.widely used in plastics. When user can't achieve brighter red color with red blue pigment,pigment blue 60 is option, costs of it increase as well.
Pigment blue 15 is most red among all phalocyanine pigments,only recommend when common heat resistance,red shade,high tinting strength is needed, for example EVA forming.
