Corrosionpedia explains Xylan
Xylan is a fluoropolymer that possess several strong C-F bonds within its chemical structure, making it highly resistant to solvent, acid, base and other chemical attacks or penetration. Over 300 grades of xylan are commercially available for corrosion protection and prevention purposes. It offers several desirable properties such as good abrasion resistance in extreme environments, water resistance, wide temperature operating ranges, flexibility for application in tight crevices without breakage, good adhesion and machinability.
