High-performance polymers such as aromatic polyimides, fluoropolymers, liquid crystalline polymers, polyaryletherketones, and sulfone polymers are widely used in automotive, aerospace, electric and electronic, industrial and medical applications that involve high temperature and extreme environment.
Even though they have a higher price compared to engineering plastics, they are chosen when their special features compensate for their cost. They are replacing conventional materials used in aerospace and automotive applications such as ceramics and metals mainly due to their lightness, high heat and oxidative resistance, chemical inertness, high dimensional stability and ability to maintain mechanical and physical properties over a wide temperature range.
In addition, these plastics can be easily molded complex geometries components, offering design flexibility to satisfy continuous demand for component miniaturization, functional integration, safety and esthetic features that lead to their use in the automotive and electric and electronic application. Continuous research and development on these plastics aim to reduce overall manufacturing cost and widen their range of applications.
