High temperature engineering plastics, as the name suggests, are a kind of hard engineering plastics with high temperature. If you want to increase whiteness, you have to use high temperature whitening agents.

High temperature plastics, engineering plastics and hard plastics all have their own uniqueness. First of all, high temperature plastics, as the name implies, are formed by high-temperature extrusion, and the plastic receives a high temperature during the firing process. Moreover, compared with traditional plastics, engineering plastics have many higher functions of cold resistance and heat resistance than ordinary plastics. Hard plastic is a kind of plastic that can not be processed again after hot pressing. These plastics also have strict requirements for the fluorescent brightener used. The high temperature resistance function of the fluorescent brightener must be ensured. If the high temperature resistance of the fluorescent brightener is not good, the plastic will lose its function before reaching the melting point.

There are many types of fluorescent brighteners. Customers who do not know about fluorescent brighteners will not be able to achieve their effects if they choose fluorescent brighteners at will. They may have some other effects on the products. Because the temperature resistance of different types of fluorescent brighteners is different. If the temperature resistance can not reach the production temperature of engineering plastics, the whitening agent will be directly burned into ash through high-temperature decomposition at the time of production, which will not only fail to achieve whitening, but also make some plastics yellow and black, affecting the function. Therefore, many manufacturers lose confidence in the whitening agent after selecting the wrong type, and even mistakenly believe that the whitening agent is useless.

The whitening agent OB-1 is commonly used by many manufacturers of engineering plastics. Its temperature resistance is also relatively high among all fluorescent whitening agents. It can withstand about 360 degrees of temperature and can meet the needs of most plastic products customers. Fluorescent brightener OB-1 is used for the molding and processing of various plastics and plastic products at high temperature. Due to its good heat resistance, light resistance and chlorine bleaching resistance, it is also ideal for the whitening of polyester fiber, cotton and other fiber blended fabrics. OB-1 can also be used for whitening plastics such as ABS, PS, hips, PA, PC, PP, EVA and rigid PVC. The addition of OB-1 to nylon fiber, nylon and polyester will also significantly improve the whiteness. Jiangmen Jianghai xinxiongli Plastic Technology Co., Ltd. is a high-tech enterprise specialized in developing, producing and selling PA (PA6, PA66) and high-temperature nylon PA46, PA6T, PA9T) pet and other modified engineering plastics. For a long time, we have been continuously committed to the development of high-tech products, so that the enterprise has developed rapidly and is in the leading position in this field. At the beginning, we joined the member units of the processing and Application Professional Committee of China Engineering Plastics Industry Association.
