Arkema PEKK
Zell-Metall Engineering Plastics Zellamid 250 (PA6.6) at 50% RH
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 66 (PA66); Nylon 66, Impact Grade

Material Notes: Zellamid® 250 is noted for its high temperature resistance and high tensile strength. It is the hardest and most rigid type of extruded Nylon. Main characteristics are high resistance to fuels, oils, greases, most organic solvents and alkalis. Moisture absorption is lower than for Nylon 6.

Typical applications are friction bearings, gears, cams and cam followers, guides, sleeves, valve seats and articles subjected to high loads and/or for high temperature.
