Function :
Pearl effect pigments can be used in nearly all thermoplastics and most processes. Their effects are most intense in transparent resins like PS, PP, PE, PVC, acrylic, styrene -block copolymers, and silicone.
It is also possible to attain in pearl pigments, pearlescence and luster in polymers having little or no transparency as with nylon 6, ABS, and HIPS but only with higher pigment loadings. Pearl effect pigments combined with dark absorption pigments in opaque polymers can yield a strong reflection color and produce pearlescent effects of great richness and depth.
