What Are Pearlescent Pigments?

Pearlescent pigments are made of layered materials like mica or synthetic substrates coated with metal oxides. These materials reflect and refract light to create a range of visual effects depending on their size, shape, and orientation in the resin. In masterbatch design, the size of the pearl—measured in microns—is one of the most critical variables to control.

Micron Size = VISUAL IMPACT

Here’s a general breakdown of how micron size affects visual output:

<20 Microns – SATIN FINISH:
Provides a soft, silky glow. Often used when a subtle, sophisticated appearance is desired. Great for packaging and automotive interiors.
20–50 Microns – SHIMMER FINISH:
Creates a more noticeable play of light without overpowering. This is the "classic pearl" look used in many consumer goods.
50–140 Microns – SPARKLE FINISH:
Adds more depth and visible movement to the surface. Perfect for parts that need to catch the eye on the shelf.
>140 – GLITTER FINISH:
Delivers bold visual impact. Larger flakes are more reflective and directional, making them ideal for decorative or promotional applications.

Why Speaking the Same Language Matters

Inconsistent terminology like “I want it to pop” or “make it shinier” can lead to mismatches in expectations between brand owners, designers, and technical teams. That’s why we developed the BADGER COLOR USA Pearlchian Tool—a hands-on resource that visually demonstrates pearl effects across different microns. Each plastic chip is labeled clearly by both size and descriptive finish (Satin, Shimmer, Sparkle, Glitter), giving everyone a shared vocabulary to work from.

When you’re specifying a pearlescent effect, it’s important to communicate:

Micron size range
Desired effect intensity
Resin type and processing method
Lighting/environment where the product will be viewed
