KetaSpire® KT-820 SP is a low flow / high viscosity grade of unreinforced natural polyetheretherketone (PEEK) that is designed for extrusion applications. The SP suffix denotes pellets (2.25 mm diameter on average), which contribute to improved feeding and conveying in small extruders and other processing equipment. KetaSpire® is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent chemical resistance, best-in-class fatigue resistance, ease of melt processing, high purity, and a host of other attributes.
These properties make it well-suited for applications in healthcare, transportation, electronics, chemical processing and other industrial uses. In addition to extrusion, KetaSpire® KT-820 SP can also be processed using injection molding processes. This material comes in pellet form  with a 0.02% dusting of a vegetable derived calcium stearate on the pellets. The calcium stearate dusting is to further aid in pellet conveyance in extruders and injection molding machines.
