The materials of the future, in particular, the ultra high performance plastics, are opening up new technical possibilities for innovative products. High performance plastics materials maintain twenty-five percent or better of their room temperature properties at 310°F (154°C) and higher, are stronger, and have important characteristics, such as chemical resistance, stiffness, fire retardance, processability, and others, to stretch the boundaries of plastics applications. Challenging applications in military/aerospace, industrial, electronics, healthcare, and down-hole oil and gas applications have created demand for ultra high performance resins that combine very high heat and chemical resistance with good thermoplastic melt processability.
