KetaSpire® XT-920 CF30 is a 30% carbon fiber reinforced grade of the industry's first true a high-temperature PEEK. This compound provides the maximum level of mechanical properties at temperatures approaching 300°C. It also exhibits the lowest coefficient of linear thermal expansion (CLTE) within the KetaSpire® XT product family.

The PEEK designation is based on the 2:1 ratio of ether-to-ketone functional groups in the polymer backbone. The material provides the exceptional chemical resistance of PEEK along with a 20°C (36°F) higher glass transition temperature and a 45°C (81°F) higher melting temperature than standard PEEK. This increase in thermal performance allows engineers to achieve higher mechanical strength for components used in higher temperature and higher pressure operating environments.

Although other high-temperature polyketones exhibit thermal properties on par with KetaSpire® XT, their chemical resistance is significantly inferior to standard PEEK and KetaSpire® XT. The material's unique combination of properties makes KetaSpire® XT well-suited for applications in oil and gas, transportation, electronics, chemical processing, and other industrial uses.
