Lightweight and easy-to-wear sports shoes have become a trend regardless of age and gender. Why are they so popular? 

First of all, let's talk about its material. There are all kinds of shoes made of various materials, generally EVA foamed shoe materials, PVC foamed shoe materials, and PP foamed shoe materials. In these shoe materials, EVA is used as a raw material. This is mainly because it should be used in sports shoes. Sports shoes are more common shoes that people wear. Almost everyone will have such a pair, and sports shoes mostly white. In the production process of shoe materials, the fluorescent brightener for foamed shoe materials is an indispensable additive. Today, I will show you what are the excellent characteristics of the fluorescent brightener used on foamed shoe materials.

The EVA foamed shoe material has the characteristics of softness, good elasticity, shock absorption, chemical resistance, etc., so it is widely used in the soles of medium and high-end tourist shoes and hiking shoes. In terms of shoe materials, EVA foaming technology is generally speaking there are three processes: traditional flat large foaming, small in-mold foaming and injection cross-linking foaming. Among them, molded foaming and injection cross-linking foaming are more used.

We must know that the influence of bubbles in the foaming of shoe materials is very important, so the fluorescent brightener must meet the production process of foaming shoe materials. Here, it is recommended to use the fluorescent  brightener KCB for foaming shoe materials. The melting point of the fluorescent  brightener KCB is exactly the temperature at which EVA is molded. In addition, KCB has a strong whitening effect, showing a bright blue light. Since shoes have been exposed to the outside world for a long time, the unique advantages of fluorescent  brightener KCB's good light resistance and heat resistance have emerged. And its addition amount is very small, generally adding about 0.01%-0.03% can have a good whitening effect, and for manufacturers, the cost is reduced a lot.

The following is brief instruction of fluorescent  brightener KCB for your reference.
