As a material, Klingersil C-4401 offers a calendered, compressed fiber structure bound with elastomer, consistent thickness and density across the sheet. It resists hydrocarbons, a broad range of process chemicals, and steam and hot water. It is not the right choice where strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope are present.

It sees regular use in pulp and paper, refining, and steam and hot water systems.
