Technically speaking, pearlescent pigment can be applied in all kinds of thermoplastic plastics and partial thermosetting plastics. From aspect of material of plastic, it can be divided into transparent and non-transparent resins. By added pearlescent pigment in resin, a fascinating visual effect is achieved.

For those lower transparent resins for example PC or PVC, due their special processing characteristics also could present pearl luster and color eventually.
