First of all, let's take a look at the types of glow in the dark powder. There are three different kinds of glow in the dark powder. They are long afterglow glow powder, zinc sulfide glow powder, and self-glow luminous powder.

In dark powders made of rare earths, alumina and strontium carbonate, the long afterglow is safest.  Does not contain phosphorus, lead and other harmful elements, does not contain radioactive substances.  As a result, it has secure and stable physical and chemical properties, which allow it to come into direct contact with people. Long after glow luminescent powder can be recycled for about 15 years.

How does long afterglow glow powder work?

Glow-in-the-dark powder is a photoluminescent material.  It absorbs UV energy for a few minutes and stores it.  The light is then radiated in the dark.

Long Afterglow powder is one of the most popular dark glow powders on the market.  Widely used in resin, rubber, plastic, printing, paint and other industries.

Zinc sulfide luminous powder is also a non-toxic luminous powder.  The biggest difference between it and long afterglow powder is that zinc sulfide absorbs light quickly.  It absorbs UV for less time, but it doesn't last as long as long afterglow powder.

Which luminous powder is poisonous?

The self-luminous powder does not require any light excitation and can emit light itself.  It is very radioactive and harmful to human health.  In addition, it has a complicated manufacturing process, so the luminous powder is now obsolete.
