The Secrets of Glow In The Dark Technology

With the development of technology, there are great varieties of exciting toys. The batteries glow toys, the ones that rechargeable, and there are fancy ones who don’t need batteries or charging; in fact, they are made of  glow in the dark powder . However, most people now have some misunderstandings or concerns about luminous products, such as luminous toys, crafts, etc. People commonly think chemical products must contain heavy metals or toxic; how can it glow? Do they have radiation and other issues? Today I will explain the above concerns. THE NEW GENERATION OF GLOW IN THE DARK POWDER DOESN’T HAVE RADIATION. It can “absorb” and “store” light energy, and emit light in the dark environment. The process of “absorb, store or emit” light is physical rather than chemical. Because radioactive materials generally do not absorb and store light before they are released, and those radioactive materials are costly. Early luminous materials were radioactive  Thorium  and  Radium  elements

Many factors can affect the glow effect of glow in the dark paint. Many people often ask us to put the luminous powder directly into their lacquer, will their lacquer be able to glow the same as our glow in the dark paint and can start construction instantly? However, glow in the dark paint is not so simple to make; we studied the viscosity for a long time to reach that balance. Also, people sometimes confused with reflective paint, luminous paint, and fluorescent paint. To determine whether it is a suitable product for you, we will introduce the differences between them one by one. This is a very professional question, and it is a problem that we need to explain repeatedly many times, which wastes both parties’ time and reduces work efficiency.  Therefore, today I will introduce the difference of three special effect paints–reflective paint, luminous paint, and fluorescent paint, as well as those questions that everyone is curious about glow in the dark paint, why it doesn’t glow b

Many of our clients reported to us that when they were trying to add lumous powder in the injection molding production, the plastic products produced became black or dark brown color. Today we will talk about the reasons why this happens and how to avoid this phenomenon. In the injection molding process, the luminous powder mainly rubs against the metal in the cavity so that the metal chips are mixed into the plastic product, which causes the plastic products to become black. THERE USUALLY ARE 2 MAIN REASONS FOR INJECTION BLACKING HAPPENS: 1. The proportion of powder is too high：normally should be below 20%. 2. The particle size of the glow in the dark powder is too big: we recommend to use glow in the dark powder particle size of 250 mesh for injection mold as per our experience. FOLLOW THE STEPS BELOW TO REDUCE THE CHANCE OF HAVING INJECTION BLACKENED PRODUCTS. PRECAUTIONS FOR LUMINOUS POWDER INJECTION 1. When mixing luminous powder and plastic, it is best to use manua
