Fluorocarbon laminate sheet lining of high chemical resistance

Among the wide selection of organic based surface coating materials, the fluorocarbon plastics have always been of particular interest for their ability to withstand aggressive chemical environments. The first widely known fluorocarbon was P.T.F.E. which has outstanding chemical resistance. Unfortunately this material is not a true thermoplastic and this fact has limited its application as a lining for tanks and vessels. Attention was turned to other fluorocarbon compounds and several alternatives have been used in industry, and although chemical resistance is slightly inferior to P.T.F.E. the chemically related fluorocarbons which possessed true thermoplasticity have been very useful to chemical engineers and those involved in the choice of lining materials. It is always attractive to the engineer to apply a suitable anti‐corrosive lining to an existing carbon steel vessel, rather than replace with an exotic material of construction. Lined carbon steel is usually a cheaper solution and much more readily available.
