PEEK KETASPIRE KT-880SFP 产品说明：
KetaSpire® KT-880SFP is the high flow grade of unreinforced polyetheretherketone (PEEK) supplied in a natural-color 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-880SFP 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-880 NT for injection molding applications.
