摘要：
The present invention provides a substantially spherical composition comprising about 60 to 80 percent by weight pearlescent pigment, 14 to about 38 percent by weight wax, and about 2 percent to 6 percent surfactant. This composition is particularly useful for extrusion into any polymer used for masterbatching. The masterbatch is then typically blow or injection molded or extruded into a finished part.
