Tufnol phenolic cotton materials are the workhorse grades for general mechanical applications. They are strong and tough with very good wear resistance and they are easy to machine into finished components.
They are available with cotton fabric reinforcements, ranging from fine weave to coarse. In general, the medium to coarse wave grades are used for larger and more rugged components, requiring good all-round strength and toughness. The finer 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 cotton fabric grades are Carp Brand and Whale Brand. >>>
