1. Physical Form and Particle Size
Pearlescent Pigments:
Pearlescent pigments are powdered materials made from natural mica flakes coated with metallic oxides to create a pearl-like luster. Their particles are relatively small, ranging from 5 to 100 microns, and appear microscopically transparent and flat. They rely on light refraction, reflection, and transmission to produce color and brightness.
Glitter (Glitter Particles):
Glitter, also known as sparkle flakes or sequins, is crafted from highly reflective PET, PVC, or OPP metalized films through electroplating, coating, and precision cutting. Glitter particles vary widely in size, from 0.004 mm to 3.0 mm, and come in shapes such as squares, hexagons, and rectangles.
2. Optical Effects
Pearlescent Pigments:
With their fine, uniform particles, pearlescent pigments produce a subtle, high-frequency light reflection, resulting in delicate, cool-toned hues (e.g., blue, purple). They are ideal for creating soft, natural highlights and blending effects in cosmetics.
Glitter:
Larger glitter particles generate lower-frequency reflections, yielding a warmer, more subdued visual tone. However, their high reflectivity delivers bold, eye-catching flashes, enhancing the vibrancy and dimensionality of decorative surfaces.
3. Weather Resistance and Chemical Stability
Pearlescent Pigments:
These pigments exhibit excellent stability, oxidation resistance, weather resistance, and chemical resistance, making them suitable for diverse environmental conditions.
Glitter:
Glitter offers moderate resistance to climate, temperature, and mild chemicals. Thermal stability varies by material: PET-based glitter withstands up to 190°C, while PVC-based types degrade at 60°C.
4. Applications
Pearlescent Pigments:
Widely used in coatings, plastics, inks, cosmetics (e.g., foundation, powder, highlighters), leather, textiles, and paper, they impart a luxurious, natural shimmer to surfaces.
Glitter:
A popular choice for decorative applications, glitter enhances Christmas crafts, candles, screen-printed textiles, furniture finishes, toys, and cosmetics. Its bold, textured sparkle adds 3D depth and dramatic contrast to designs.
Summary
Pearlescent pigments and glitter differ significantly in particle structure, optical behavior, durability, and applications. Understanding these distinctions ensures optimal material selection for desired aesthetic and functional outcomes.
