When Pearlescent Pigments are
used as colorants for plastics or masterbatches, the user must understand
theproperties of Pearlescent Pigments, and make correct production process
arrangement. Then you could get satisfied and most beautiful colors. Generally
speaking, the production of Pearlized masterbatches and colored masterbatches
are similar, but there are some suggestions during the application as below:
1. Temperature resistance of pearlescent pigments: up to 800℃ .
2. It can bring out the widest spectral purpose by
blending the pearlescent pigments with other transparent dyes or pigments,
while avoid blending the pearlescent pigments with other opaque pigments.
3. Suggest to blend other transparent dyes or pigments evenly
before adding the pearlescent pigments in them.
4. Avoid blending different codes of pearlescent
pigments.
5. Forbid grinding the pearlescent pigments.
6. Forbid stirring the pearlescent pigment for a long
time in high speed blender.
7. Suggest to stir the pigments with transparent or
semi-transparent plastics resins evenly before pouring them.
8. The additive proportion of pearlescent pigments and
plastics resins is: 1:10~3:10(according to the different requirements).
9. Suggest to use single screw
extruder, while avoid using double screw extruder.
