**Yu Mingjie Technology - A Comprehensive Overview of Pearlescent Pigments and Their Applications**
Pearlescent pigments are a modern type of powder pigment that replicate the elegant luster and colors found in natural pearls, shells, butterflies, fish, and metals. These pigments offer a glossy finish, are non-toxic, odorless, resistant to acids and alkalis, non-flammable, non-explosive, non-conductive, non-migrating, easy to disperse, and highly heat- and weather-resistant. They meet strict environmental standards and provide a safe, versatile option for various industries.
What makes pearlescent pigments unique is their ability to mimic the shimmer of metallic pigments while also offering the soft, natural hues of pearls. Unlike traditional metallic pigments, their reflective effect is passive — they only shine when exposed to light. This gives them a subtle yet striking visual appeal.
There are several main types of pearlescent pigments, including natural fish scale-based, bismuth oxychloride crystal, and mica-coated varieties. Among these, mica-based pigments are the most widely produced and used globally. These pigments are made from natural mica flakes (ranging from 4μm to 120μm in size) coated with multiple layers of titanium or other metal oxides through advanced chemical processes.
**Classification of Pearlescent Pigments**
Pearlescent pigments can be categorized into several series, such as silver white, iridescent (interference), gold, colored, and mica iron. Each category offers different visual effects and color variations. The principle behind their beauty lies in the way they interact with light — through refraction, reflection, and transmission — to create a soft, pearly sheen that mimics the look of real pearls.
