KetaSpire® KT-851 NL resin is a depth-filtered grade of polyetheretherketone (PEEK) supplied in non-lubricated, natural-color pellet form and is specially designed for use in extruded wire insulation coating. KT-851 NL offers the needed balance of properties and processability for applying thin insulation coatings onto copper or other conducting wire using a continuous extrusion process to achieve a robust insulation coating that is capable of withstanding the harsh use environments of many industrial applications. KetaSpire® PEEK is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent chemical resistance to organics, acids and bases, best in class fatigue resistance, excellent wear resistance, ease of melt processing and high purity. A lubricated form of this resin is available as KT-851 in natural color (NT). The pellets in the lubricated versions are supplied with a very light dusting (0.01%) of calcium stearate to aid with conveying through single screw extruder-based processing equipment. |

| 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. |
