So, it is worth noting, Tufnol phenolic cotton Materials are the workhorse grades for electrical and general mechanical applications. Furthermore, they are strong and tough with very good wear resistance and they are easy to Machine into finished Components.

Certainly, available are Tufnol Sheets with cotton fabric reinforcements. Thus, ranging from fine weave to coarse. Hence, in general, the medium to coarse wave grades is 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.

Please note, the electrical properties tend to be superior in the finer weave grades, but the range includes a medium fabric weave. Hence, it has, enhanced electrical properties, suitable for electromechanical application. Indeed, two of the most widely used Tufnol cotton fabric grades are, Carp Brand and Whale Brand.
