Duro-Bond ETFE

Chemical Resistant, Corrosion Resistant, Good Abrasion Resistance, Good Bonding Strength, Good Smoothness, High Purity, Low Permeability, Service Life Extension

Duro-Bond ETFE is used as a vessel lining material to provide chemical resistance to acids, bases, oxidizing agents, organic solvents and other corrosive media. Duro-Bond ETFE can be applied to tanks, scrubbing towers, reactors, valves, columns, agitators and other process equipment for handling corrosive materials.. When a combination of chemical, temperature, abrasion and permeation resistance is required Duro-Bond ETFE may be the optimum solution to the corrosion problem.

Duro-Bond ETFE fluoropolymer sheet lining exhibits outstanding chemical resistance, being virtually unaffected by many of the corrosive chemicals commonly encountered in the chemical process industry.; Duro-Bond ETFE is resistant to strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and essentially all organic solvents. Typical of the fluoropolymers, ETFE is attacked by metallic sodium and potassium. Rate of attack is a function of exposure time and temperature.; Duro-Bond ETFE sheet lining provides substrate protection by virtue of its excellent permeation resistance. The ETFE fluoropolymer has low permeability to water vapor and various other gasses. The ETFE fluoropolymer also exhibits low permeability to liquid chemicals.; Duro-Bond ETFE does not contain any fillers or plastizers to leach out and contaminate the service thereby making it an excellent choice for handling high purity chemicals.

Duro-Bond ETFE sheet lining can be shop or field repaired. The repairs to defective or damaged areas in the sheet lining are accomplished by cutting out the faulty area, grinding or grit blasting the substrate surface, preparing a piece of sheet of the same dimension, cementing it into position and subsequently welding the joints as described under Application. The repaired area is then inspected and spark tested to insure lining integrity.
