Tufnol CNC Machined Parts


Tufnol is a Trade Name – Of which, 6F45 is Just one Type

Most noteworthy, ® Tufnol 6F45 Epoxy cotton grade has a unique combination of properties. Hence, making it particularly useful for applications requiring extra performance.  Especially relevant, is the good all-round performance, good dimensional stability and outstanding machinability. Finally, its principal features are its excellent electrical properties,


Further, ® Tufnol 6F45 is made with a specially modified Epoxy resin. Thus, gives a high Insulation resistance and electric strength. But also, exceptional resistance to surface electrical tracking. Also, first class electrical properties, which, when combined with the excellent wear resistance, of fine weave cotton, provide, a combination of properties not found in other grades.

Most notably, grade ® Tufnol 6F45 is mechanically strong. And, resistant to a wide range of chemicals.  Furthermore, it has low water absorption and good dimensional stability. Resulting in, a fine tolerance and a superb, Machined finish to Materials, such as 6F45.

Certainly, virtually all laminated Engineering Industrial Plastics Materials can be Machined and Fabricated at Sentinel Plastics.
We are a Company offering our customers a wealth of knowledge. Thus, covering the huge range of Engineering Industrial Plastic Materials. Available in, Sheet, rod, Fabricated and Machined form.

Impressively, Sentinel has Five Engineering Industrial Plastics CNC Routing Machines. All of which, can produce any cut shape. From the extensive range of Industrial Plastics available in today’s market.  Visit our Engineering Materials Page.

Tufnol 6F45 Machining Specialists

With Tufnol, phenolic cotton Materials are the workhorse grades for general mechanical applications. Further, they are strong and tough with very good wear resistance. Also, easy to Machine into finished Components.

Tufnol Sheets are available with cotton fabric reinforcements. These, range from fine weave to coarse. In general, the medium to coarse weave grades are used for larger and more rugged Components, Thus, 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.

Also notable, 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. Notably, the two most widely used Tufnol cotton fabric grades are: Carp Brand and Whale Brand.

Further, Phenolic cotton grades available for Machining:
