Problems solved by technology

With the continuous development of industry, the requirements for high temperature resistance of materials are getting higher and higher. In order to solve such problems, materials are required to have good dimensional stability, high strength, and high temperature resistance. At present, high temperature resistant reinforced nylon is relatively One of the ideal materials, but the specificity is large and the cost is high, so the use is limited
[0003] At present, in order to further expand the application field of polycarbonate and solve the problem of high temperature resistance of PC materials, it has become the research direction of many enterprises. PC high temperature resistance is usually modified to solve the high temperature resistance requirements of PC materials during use. , the commonly used method is to add high-temperature resistant additives to PC materials to solve the problem. Although the effect is very ideal, the development cost is very high, and it is not very popular in the material selection process of enterprises.
