First, consider the particle size , which determines whether it can meet the product requirements and production process. After that thinking about the luminescence features , selecting the one that suits the product application scenario ( charging speed, initial brightness, and afterglow duration ). Finally, choose the color (body color and luminous color) .
, you can choose the most suitable photoluminescent powder for your product.
However, does a product made with the brightest powder necessarily have the highest brightness? The answer is not necessarily. This article will explain in detail how, as a
For example, in screen printing, the particle size of the photoluminescent powder must be smaller than the mesh size to ensure all the luminescent ink can pass through. Similarly, when spraying paint, the particle size of the photoluminescent powder must be smaller than the nozzle diameter of the spray gun, otherwise it will clog the nozzle. When making ultra-thin coatings or ultra-fine cables, the maximum particle size of the photoluminescent powder must be smaller than the coating thickness or cable diameter. Therefore, when choosing the particle size of the photoluminescent powder, it is crucial to understand the production process.
Even If The Particle Size Fits The Process Requirements, Larger Particles Do Not Always Perform Better.

The characteristic of photoluminescent powder is that the larger the particle size, the higher the brightness. However, when choosing photoluminescent powder, choosing larger particle sizes doesn't always lead to better brightness. A key concept here is the coverage. Larger particles have higher brightness, but their coverage is not as good as that of smaller ones. When applied to products,
Sometimes smaller particle powder performs better. The final product may show a more translucent and even brighter effect . Professional suppliers have more experience in finding this balance.
Some customers want to choose large particles and grind them according to their needs. It is important to note that it is not feasible because the
grinding process will damage the surface of the photoluminescent powder particles, causing them to lose their luminescent effect. Therefore, you can only choose according to the existing particle sizes.
