PF401 is a high end specialty black, it provides significant advantages to fine denier polyester fiber spinner & masterbatch producers. Its ultra physical cleanliness increases melt fiber life by reducing plugging resulting in low production cost fiber manufacturing. Morphological properties of PF401 are balanced in such a way that it provides a good combination of blue tone, dispersibility and color strength with extremely low filterability. With PF401, high spin pack life can be achieved by polyester fiber producers. It provides very low consistent fine screen Delta P in PET, PBT & PP base polymers.
