1. What is Plastic-Specific Glow in the Dark Powder?

Plastic-Specific Glow in the Dark Powder is specifically designed for the plastic products production. Comparing to normal glow in the dark powder, it is more suitable for plastic material production by injection molding, extrusion, blow molding, rotational molding and etc.

2.Why is it necessary to develop Plastic-Specific Type?

Glow in the dark powder is widely used in plastic products, ranging from safety signs, toys, tableware, and handicrafts, covering multiple industries. However, after mixing it with plastic raw materials for production, the final product is prone to blackening. The blacken issue not only affects the body color of the product, but also lower the glow brightness.

The key reason for the blackening issue is High Friction.

The normal type of glow in the dark powder particles exhibits a relatively high hardness, which can easily cause friction with solid plastic raw materials, screws and the barrel inner walls during processing, forming impurities that mixing into the final product. To solve this problem, we have developed a special type with higher lubricity, which can minimize friction and thus alleviate blackening. In addition, by adjusting production parameters (such as mixing speed, melting rate, injection speed, etc.) to minimize friction as much as possible, the success probability of the final product will be greatly increased.

3. Applicated Plastic Types and Techniques of Plastic-Specific Powder

3.1 Acceptability Plastic Types：PP, PE, PET, ABS, PLA, TPR, PC, PVC，PS, Sarin, etc.,

3.2 Applicable Processing Techniques：Injection molding, extrusion, blow molding, rotational molding, and etc.

4. Color Options of the Plastic-Specific luminous Powder

4.1 Three Nature Colors：Yellow-Green (Top Recommendation), Sky-Blue（Secondary Choice）, Blue-Green(Less Advisable).

These three colors have yellowish-white body color in day time. In terms of luminous performance, they emit light more brightly and have a longer afterglow than other colors. If your product has no objection to a yellowish-white daytime body, these three natural colors are preferred.

glow in the dark three nature color

Yellow-Green：Top Recommendation

Yellow-Green color is the most widely chosen option, which has the highest luminous brightness, the longest afterglow duration, and a higher probability of successful production.

Sky-Blue：Secondary Choice

In terms of both luminous brightness and afterglow duration, the performance of Sky-Blue is not as good as Yellow-Green. But if you are keen on blue tones, you can try this color.

Blue-Green：Less Advisable

The particle hardness of Blue-Green is higher than the other two colors. It is much easier to generate significant friction with equipment and materials during mixing and production processing, resulting in blackening of the product.

If you really have a special interest of Blue-Green color, only the Ultra-Fine type are possible to be tried. Under the same production conditions, compared to ordinary particles, the friction generated by ultra-fine particles is relatively small. However, it should be noted that its cost is significantly higher compared to ordinary ones due to the complex production of this type.

Noted: Dyed Color Series is NOT recommended to use directly.

Dyed Luminous Powder

* The demand of some products is to present colored body color during daytime, then customers usually want to choose Dyed Color Series to achieve this goal.

However, it is not quite recommended to use them directly in the production of plastic products. Direct usage is prone to get uneven dispersion. Furthermore, there is a relationship of one decreasing while the other increasing between the colorful body color and the luminous effect. The adjustment is complicated. A better solution is to take natural colors luminous powder, and in customer’s plastic production process, add their own dyes (such as fluorescent powder, color paste, dyeing pigments, etc.) for color adjustment. Through this operation, not only the body color and luminous effect can be adjusted in time according to the actual needs, but also to ensure that the end product presents a uniform color appearance.

6. Storage for Plastic-Specific luminous Powder

Plastic-specific powder needs to be stored in a cool, dry place. Due to its strong hygroscopic properties, it should be kept away from high-temperature and humid environments. Additionally, the packing bags must be tightly sealed. Otherwise, after absorbing moisture, it is prone to hydrolysis and lose its luminous effect.

7. Adjusting the production equipment is also necessary.

In order to have the best glow effect, it’s better to take every possible method to reduce the friction.

So except using the plastic-specific glow in the dark powder, it is also necessary to adjust production equipment. For example, reducing the mixing speed, increasing the melting rate, and lowering the injection speed, etc.
