Syensqo (Solvay Specialty Polymers) KetaSpire® KT-820 NL PEEK, Low melt flow for extrusion and injection molding
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK)
Material Notes:	Low melt flow for extrusion and injection molding, not lubricated KetaSpire® KT-820 NL is a low flow grade of unreinforced polyetheretherketone (PEEK) supplied in non-lubricated, natural-color 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. This resin is also available as KetaSpire® KT-820P in a natural-color coarse powder form for compounding. A lubricated form of the resin is available as KT-820 in either natural (NT) or black (BK 95). The lubricated version is lightly dusted with calcium stearate (0.01% level) to aid with pellet conveyance in plastication screws. Applications: Aircraft Applications; Automotive Applications; Electrical/Electronic Applications; Film; Industrial Applications; Medical/Healthcare Applications; Oil/Gas Applications Features: Chemical Resistant; Ductile; Fatigue Resistant; Flame Retardant; Good Dimensional Stability; Good Impact Resistance; High Heat Resistance Standard Packaging and Labeling - KetaSpire resins are packaged in polyethylene buckets or cardboard boxes depending upon the order size. Individual packages will be plainly marked with the product, color, lot number, and net weight. Injection notes: Drying - KetaSpire resins must be dried completely prior to melt processing. Incomplete drying will result in defects in the formed part ranging from surface streaks to severe bubbling. Pellets can be dried on trays in a circulating air oven or in desiccating hopper dryer. Drying conditions recommended are 4 hours at 150°C (300°F) . Injection Molding - KetaSpire resins can be readily injection molded in most screw injection machines. A general purpose screw with a compression ratio in the range of 2.5 - 3.5 : 1 is recommended, as is minimum back pressure. Injection speeds should be as fast as possible, consistent with part appearance requirements. Mold temperatures in the range of 175°C to 205°C (350°F to 400°F) are suggested. Recommended starting point barrel temperatures are shown in the following table. Information provided by Solvay Specialty Polymers.
