After any product is produced and stored for a period of time, the surface color or luster is not as bright as when it was just produced. This is unavoidable for any manufacturer, but a dull and matte product will make customers think it is old goods that have been stored for many years may even be mistaken for second-hand products, so how to avoid or reduce the occurrence of this problem? The best answer is Brightener.


In our daily life,Brighteners are divided into three categories

I.     Covering Brightener

III. Optical brightener


And optical brightening is our brightener product.As a non-toxic and harmless industrial product, optical brightener has been widely used in plastics industry,textile industry,paper making  industries. It only needs dozens of grams to make hundreds of kilograms and tons of raw materials times whiteness,showing a more vivid appearance and staying longer. So what is the principle of optical brightener?Human eyes generally can only see light with a wavelength of 400 to 700 nm. This wavelength is called the visible band, and this light is called visible light. When the light in the visible band is split, the light that changes from blue-violet (short wavelength) to red (long wavelength) can be seen, which is called the spectrum. Mix all these lights in a certain proportion and the product will look white.


How to choose a optical brightener agent and how much to use is different. Different products in different industries and even different countries use different brighteners. Of course, as an optical brightening supplier, you can consult us, or ask your local supplier related issues.
