When used together with the resin production, UNICO pearlescent pigments neither change color in resin processing, nor bloom or melt in resin system due to it's stable chemical property.  

And as non-metallic pigments, UNICO pearlescent pigments make any chemical action with neither free residual acids and bases nor reactive gene in resin, nor plastic additives, so it has better security. Therefore, pearlescent pigments are applied to transparent or translucent plastic, such as PVC, PP, PE, etc. 

The soft pearlescent luster can be obtained when the pearlescent pigments are added to plastic in correct proportion. Add white mineral oil or plasticizers as humectants of resin particle in plastic prior to production, and then add the pearlescent pigments and stir to mix well to ensure the excellent dispersibility. 

When use the pearlescent masterbatch, it is suggested to process pearlescent masterbatch before production. The addition proportion of pearlescent masterbatch can be flexibly calculated according to the content of pearlescent pigment in pearlescent plastic, and then directly mix with resin.
