KetaSpire XT-920 NT Polyetheretherketone Syensqo PEEK Pellets

PEEK KetaSpire XT-920 is an unreinforced, natural color grade of the industry's first true high-temperature PEEK polymer supplied in a lubricated pellet form. 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. KetaSpire XT also provides a significant improvement in electrical properties.

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 & gas, transportation, electronics, chemical processing, and other industrial uses. KetaSpire XT-920 can be easily processed using typical injection molding and extrusion processes. This resin is also available as KetaSpire XT-920P in a natural-color coarse powder form for compounding.

Pellets of KetaSpire XT-920 are supplied lightly dusted with the lubricant calcium stearate (0.01% level) to aid with pellet conveyance in plastication screws. The equivalent non-lubricated, natural color grade is KetaSpire XT-920 NL.
