　　Among the numerous plastic products on the market, there are various materials available, roughly divided into three categories: hard plastic, semi soft plastic, and soft plastic. These three types of plastics are commonly used around us, and various additives are added to their products in the processing technology, especially white products, which will add whitening agents.

　　There are only a few manufacturers of whitening agents for plastics in the world, but there are thousands of customers who make plastics everywhere, large and small. Almost every plastic consumer manufacturer will use whitening agents, but the model and price of whitening agents are different. There are also many dealers that make whitening agents in the world. They mainly supply some plastic manufacturers in other places, and buy when you use them. Now since the Internet, the price of fluorescent whitening agents in the market is clear, but the price of whitening agents sold by dealers is not very high, and they think there is no profit to be made. Here, only the purity of the products should prevail.

　　Fluorescent whitening agents mainly use the principle of optical whitening and color fading to improve the glossiness and integrity of the product when produced. They are widely used in the five international general plastics and various engineering plastics. Especially in plastic granulation, the reaction in plastic products is relatively good. It is recommended to add 10-30 grams per 100 kilograms and mix thoroughly with the raw materials to make the produced plastic different from its peers and have good market competitiveness.
