OKUSLIDE® Tough Blue - FN5874

OKUSLIDE® Tough Blue – FN5874 is an exceptionally wear-resistant material (UHMW-PE with approx. 8 - 9 million g / mol). Its special formulation gives the material a very high wear resistance. A low coefficient of sliding friction, a long oxidation resistance and simultaneous UV protection allow the application in a variety of applications.

Properties:

• extremely wear resistant
• good sliding properties
• good chemical resistance
• low maintenance
• improved life time compared to standard UHMW-PE
• heat stabilized
• EU1935/2004 - conform
• EU10/2011 - conform

food-grade
