Due to its high mechanical properties and wear resistance, PEI black plastic is widely used in the manufacturing of high-speed rotating components and parts that require extremely high smoothness. For example, PEl black plastic can be used to manufacture automotive engine components, aerospace components, electronic and electrical components, etc. In addition, due to its excellent chemical resistance, PEI black plastic can also be used to manufacture products such as chemical equipment and pipelines.
The main physical parameters of PEI black plastic include density, hardness, melting point, glass transition temperature, coefficient of thermal expansion, thermal conductivity, wear resistance, and friction coefficient. Due to the high wear resistance and friction coefficient required for PEl black plastic, its hardness and thermal conductivity are usually higher, while its melting point and glass transition temperature are lower. In addition, the density of PEI black plastic is usually higher, which helps to improve its mechanical properties.
With the continuous development of technology and the increasing demand for high-performance materials, PEI black plastic, as a high-performance engineering plastic, has a very broad market prospect. According to market research institutions' predictions, the global polyetherimide market will maintain a rapid growth rate in the coming years, with the Asia Pacific region becoming one of the largest markets. Therefore, PEI black plastic, as an application form of polyetherimide, will also have broad market prospects.
