Product Highlights
  • Tufnol Grade 6F/45 is made with a specially modified epoxy resin, which gives it high insulation resistance and electric strength, and an exceptional resistance to surface electrical tracking.
  • These first-class electrical properties, with the excellent wear resistance of the finer weave cotton, together provide a combination of properties not found in other grades.
  • Grade 6F/45 is mechanically strong and is resistant to a wide range of chemicals.
  • It has low water absorption and good dimensional stability, giving fine tolerances and a superb machined finish.
