Used primarily as a high-performance thermoplastic in engineering applications, this chemical contributes to the production of materials with excellent heat resistance, dimensional stability, and mechanical strength. It is commonly employed in the manufacturing of electronic components, such as connectors and insulators, due to its ability to withstand high temperatures during soldering processes. Its inherent flame retardancy makes it suitable for applications in the transportation and construction industries where fire safety is critical. Additionally, it is utilized in composite materials for aerospace and automotive parts that require lightweight, durable, and thermally stable components. The polymer also finds use in membranes for gas separation and filtration systems owing to its rigid structure and chemical resistance.
