Why is it not white to add fluorescent brightener?

White plastic products have always occupied the dominant position in many color plastics. In order to achieve the white and bright effect in the production process of white plastic, we often add a small amount of fluorescent whitening agent to improve the appearance of products. However, some manufacturers will tell us that the same problem is that the products made by themselves with fluorescent whitening agents have not achieved an ideal whitening effect, while the effect of others is more obvious. What is the reason? Today Shanghai enmai will solve this problem for you.

 

1. The selected fluorescent brightener is not suitable

 

At present, there are many types of fluorescent whitening agents used in plastics. The types of fluorescent whitening agents are different, so their appearance, melting point, heat resistance, compatibility and weatherability are also different. Once the manufacturer does not choose the right fluorescent whitening agent, it is difficult for the whitening agent to produce its due effect.

 

There is also an important point is to ensure the quality of fluorescent whitening agent, after all, the content of whitening agent in the market is chaotic, the phenomenon of shoddy is common.

 

2. The amount of fluorescent brightener is not suitable

 

Any good product dosage is not the more the better, if the fluorescent whitening agent exceeds the recommended dosage, it not only can not play a whitening effect, but will appear yellow, or whitening agent precipitation!

 

However, if the amount of it is too small, it can not achieve good whitening effect, so the dosage still needs to be tested in the early stage to find an accurate amount.
