| KetaSpire® KT-820 is a low flow grade of unreinforced polyetheretherketone (PEEK) supplied in a lubricated pellet form. KetaSpire® PEEK is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent wear resistance, best-in-class fatigue resistance, ease of melt processing, high purity, and excellent chemical resistance to organics, acids, and bases. These properties make it well-suited for applications in healthcare, transportation, electronics, chemical processing, and other industrial uses. KetaSpire® KT-820 can be easily processed using typical injection molding and extrusion processes. This resin is also available as KetaSpire® KT-820P in a natural-color coarse powder form for compounding. Pellets of KT-820 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 of low flow KetaSpire® is available as KT-820 NL. Black: KT-820 BK 95 Natural: KT-820 NT&& |
