| KetaSpire® KT-820SFP is the low flow grade of unreinforced polyetheretherketone (PEEK) supplied in a natural-colored, super-fine powder form. This super-fine PEEK powder is suitable for water-borne coatings, electrostatically driven powder coatings, and resin pre-impregnation of continuous fiber composites. This super-fine powder is produced to a median particle size D50 of about 30 micrometers. KetaSpire® PEEK is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent chemical resistance to acids, bases and a broad range of aggressive organic chemicals, best in class fatigue resistance, high thermal resistance, high purity and ease of melt processing. These properties make KT-820SFP well-suited for applications in health care, transportation, electronics, chemical processing and other industrial uses. The resin is also available in a natural-colored pellet form under the grade name KT-820 NT for injection molding and extrusion&& |
