产品描述
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.
