KetaSpire® KT-810

About
PRELIMINARY DATA SHEET KetaSpire® KT-810 is an ultra-high molecular weight natural PEEK resin having a melt viscosity ranging from 0.51-0.65 kPa-s as compared to 0.38-0.50 kPa-s for standard high-viscosity PEEK grades such as KT-820. 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; exceptional retention of mechanical properties up to 240°C (464°F); best-in-class fatigue resistance; excellent wear resistance; ease of melt processing; and high purity. The KT-810 grade achieves a greater level of mechanical toughness than previously possible with PEEK, yet it is still processable by conventional methods including extrusion, injection molding, and compression molding. KetaSpire® KT-810 is particularly suited for compression molding applications such as machined parts and stock shapes wherein the inherent slow cooling rates of the process limit PEEK’s toughness and often result in brittleness due to the higher crystallinity levels. The grade is available in two forms: fine powder with average particle size of approximately 50 micrometers (µm) for compression molding, and pellet form for extrusion and injection molding. The fine powder grade is designated KT-810FP while the pelletized product is available as KT-810 NT. Fine Powder: KT-810 FP Natural Pellet: KT-810 NT&&
