Some general information, from the ® TUFNOL website, about synthetic resin bonded fabrics for engineering applications and Machined components.




Tufnol is a Trade Name – 6F45 is Just one Type

Firstly,® TUFNOL 6F45 epoxy cotton grade has a unique combination of properties, which makes it particularly useful for applications requiring extra performance.  Especially relevant is the good all-round performance, good dimensional stability and outstanding machinability. While its principal features are its excellent electrical properties, .

Secondly,® Tufnol 6F45 is made with a specially modified epoxy resin. Which, importantly, gives a high insulation resistance and electric strength also exceptional resistance to surface electrical tracking.  These first class electrical properties, combined with the excellent wear resistance of the finer weave cotton, provide a combination of properties not found in other grades.

Most noteworthy, grade ® Tufnol 6F45 is mechanically strong and ultimately resistant to a wide range of chemicals.  Furthermore, it has low water absorption and good dimensional stability. As a result giving fine tolerances and a superb machined finish.

Most noteworthy, Tufnol phenolic cotton materials are the workhorse grades for general mechanical applications. Furthermore, they are strong and tough with very good wear resistance and they are easy to machine into finished components.

Also, Tufnol Sheets are available with cotton fabric reinforcements, ranging from fine weave to coarse. And so, in general, the medium to coarse wave grades are used for larger and more rugged components, requiring good all-round strength and toughness. Similarly, the finer tufnol fabric grades are chosen for their superior finish, higher dimensional stability and improved strength in thin sections.

The electrical properties also tend to be superior in the finer weave grades, but the range includes a medium fabric weave, with enhanced electrical properties, suitable for electromechanical application. The two most widely used tufnol cotton fabric grades are Carp Brand and Whale Brand.
