What materials is Sparkle powder usually made of?

Sparkle powder is a type of effect pigment, usually made of various materials that can reflect light to produce flickering, shining, or flashing effects. There are various materials used to make Sparkle powder, and the following are common types of materials:

Mica: Mica is a mineral with a sheet-like structure, commonly used in the production of sparkle powder. It has good reflective performance and can decompose into small flake like particles during processing, resulting in a flashing effect.
Glass: Some sparkle powders are made of fine sand or finely crushed glass particles. These particles have a smooth surface that can effectively reflect light and produce a sparkling effect.
Metal: Some sparkle powders contain metal particles, such as aluminum or copper powder. These metal particles can reflect light under illumination, forming a unique flickering or metallic luster effect.
Plastic: Some plastic materials can also be used to make sparkle powder. Through special processing techniques, plastic particles with a shiny effect can be produced, which are used in various decorations, handicrafts, and cosmetics.
Other additives: In order to enhance the effect or change specific physical properties, other additives such as thickeners, tougheners, or pigment additives may be added when manufacturing sparkle powder.

These materials can be used alone or mixed together to produce various types and colors of sparkle powder. When manufacturing flash powder, the key is to ensure the uniformity and consistency of particle size, as well as appropriate processing techniques, to ensure that the final product has a consistent flash effect.
