Rare Earth Export Controls Suspended: Glow in Dark Powder Can Be Exported Normally!

Rare Earth Export Controls Temporarily Suspended for Another Year: Rare Earth-Based Glow in Dark Powder Can Now Be Exported Normally!

Therefore, rare earth-based Glow in dark powder from China can now be exported normally!

However, some customers don't understand why rare earth export controls affected the export of glow in dark powder samples and bulk orders. Here, let me provide a simple explanation.

What is rare earth glow in the dark powder?

Glow in dark powder (strontium-aluminate glow powder), also known as long-afterglow rare earth phosphorescent material, is a light-emitting material that automatically glows in the dark. It absorbs visible light to store energy and releases light. It saturates after 20-30 minutes of light absorption, emits light for 8-12 hours, has a lifespan of over 20 years, and can be formulated in various colors such as green, blue, purple, red, and white. This formula is commonly used in industrial-grade luminescent materials (suitable for over 20 fields including coatings, inks, plastics, and ceramics; injection molding addition ratio is 1%-20%).

How to produce glow in the dark powder by rare earth?

Essentially, it's a luminescent material made by using alkaline earth aluminates as a base (strontium aluminate and alumina are melted at 120 degrees Celsius to form a honeycomb crystalline structure), incorporating rare earth elements (using 17 rare earth elements such as europium, dysprosium, lanthanum, cerium, and praseodymium as raw materials through a sintering process). Europium and dysprosium create cavities in the alumina tetrahedral voids to store light. Rare earth Glow in dark powder does not contain harmful heavy metals such as lead and cadmium, nor does it contain radioactive elements. It fully complies with RoHS environmental standards and has low light decay, reducing waste disposal pressure.

Therefore, it can be seen that rare earth elements are an important component of aluminate-type glow in dark powders.

Then some customers might ask, are there only rare earth glow in dark pigments?

Of course, we also supply zinc sulfide-based glow in dark powder, which is commonly used in inexpensive luminescent materials for home decoration. However, this type of Glow in dark powder is no longer the mainstream product. It does darken over time, and its light-retention performance drops sharply after three months, which is related to the hydrolytic properties of sulfides.

Finally, many people may wonder: what if the US launches another tariff war against China, and China again restricts rare earth exports?

Currently, iSuoChem is actively applying for a dual-use item license for the export of rare earth Glow in dark powder. We believe that we will be able to obtain the license before the next round of rare earth controls, allowing for the normal export of Glow in dark powder.
