The outstanding feature of the Premier range is the excellent colour consistency offered by a specification of ΔE 0.5 maximum (dry versions 0.75). Products available in this range are:-
|Ultramarine blue||Premier GS||Strong green shade|
|Premier GM||Medium strength green shade|
|Premier RX||Very strong red shade|
|Premier RS||Strong red shade|
|Premier RM||Medium strength red shade|
|Premier AR||Acid resisting|
|Ultramarine violet||Premier VB||Very blue shade |
|Premier VX||Blue shade |
|Premier VU||Red shade |
|Manganese violet||Premier VM||Blue shade|
|Premier VT||Red shade|
Premier DGrades in the Premier D series are specially processed to give extremely low levels of moisture. This enables high pigmentation level concentrates to be produced without any sign of porous extrudate, even if efficient extruder venting is not available. The extra processing applied to grades in the Premier D range reduces the moisture content to extremely low levels (0.05% maximum).
Products available in this range are:-
|Ultramarine blue||Premier DXSG||Premier XSG|
|Premier DGS||Premier GS|
|Premier DXSR||Premier XSR|
|Premier DRX||Premier RX|
|Premier DRS||Premier RS|
|Premier DRM||Premier RM|
|The special manufacturing process applied to the Premier D range also minimises the trace sulphur levels remaining in the pigment after manufacture. This leads to the complete elimination of the characteristic odour sometimes associated with the processing of ultramarine pigments under certain conditions. This results in a better working environment and complete absence of any residual odour in finished plastic parts. |
Premier FSince standard ultramarine pigments include a small proportion of oversized particles, they are not recommended for fine fibre and very thin film applications. However by applying a special process to these Premier grades, a pigment with very fine particle size is produced. Grades from the Premier F range can be safely used in fibre applications as fine as 2 dtex.
Fine fibres and thin films require high strength colorants, therefore the Premier F process is applied only to the superior strength red shade blues.
The products available are:-
|Premier F||Based on|
|Premier FRX||Premier RX|
|Premier FVU||Premier VU|
|The excellent dispersion and freedom from oversize agglomerates is confirmed using an additional quality control test. The pigment is extruded through a very fine filter pack and the build up in pressure (Delta P) caused by oversize particles blocking the screen is measured. |
The final particle size of Premier FRX and the absence of particles above 10µm in size ensure the mechanical strength of the host polymer is maximised in injection moulding and extruder applications. Premier FRX is recommended for applications in which properties such as impact resistance and tensile strength are of paramount importance.
By combining the D (dry) and F (fine particle) treatments an ultramarine with a very special combination of properties is obtained. The dry nature lends itself to the colouring of moisture sensitive polymers, such as PET, while the fine particle size maximises the transparency for applications such as mineral water bottles.
