Chesterton 328 is a chemical packing completely inert to all materials except molten alkali metals. It is capable of handling high shaft speeds because of the inclusion of Chesterton’s exclusive “blocking agent”. Shaft scoring is virtually eliminated with the development of this soft PTFE form. Chesterton 328 fibers have been preshrunk and braided in our interbraid construction to give greater dimensional stability at elevated temperatures. Additionally, PTFE and other lubricants are incorporated into the fibers to resist migration.
