When making glow in the dark powder plastic products, people usually focus on the nature of the material, but ignoring the transparency of it. In fact, the transparency of plastic materials has a great impact on the luminescent effect of the final product. Opaque plastic materials with solid color will limit the light transmission and diffusion of the glow in the dark powder, and the body color of itself will also cover the brightness of the glow in the dark powder, thus reducing the luminescent effect. Transparent and semi-transparent plastic materials can transmit and diffuse light much better, which is beneficial for improving the luminescent brightness.

Transparent ABS

Solid color ABS

Taking ABS material as an example. We compared two sets of samples made with transparent ABS-TP and solid ABS-S. We added the same proportion of glow in the dark powder in both of them. It can be clearly seen that the luminescent effect of ABS-TP is much better than ABS-S.

Day effect

Glow effect

Of course, for some special application requirements or customization of body color, it is also possible to choose opaque plastic materials with solid color. However if it is optional, it is recommended to prioritize transparent substrates to achieve better luminescent effects.
