Duro-Bond E-CTFE

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

Duro-Bond E-CTFE is used as a vessel lining material to provide chemical resistance to acids, bases, oxidizing agents, organic solvents and other corrosive media. Duro-Bond E-CTFE 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 E_x0002_CTFE is often a cost-effective solution to severe corrosion problems.

Duro-Bond E-CTFE 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 E-CTFE is resistant to strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and essentially all organic solvents. Typical of the fluoropolymers, E-CTFE is attacked by metallic sodium and potassium. Rate of attack is a function of exposure time and temperature.; Duro-Bond E-CTFE sheet lining provides substrate protection by virtue of its excellent permeation resistance. The E-CTFE fluoropolymer has extremely low permeability to water vapor and various other gasses. The ECTFE fluoropolymer also exhibits low permeability to liquid chemicals. It also has excellent resistance to abrasion.

Duro-Bond E-CTFE 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.

All lined surfaces are visually inspected for surface defects. Any special dimensional tolerances required after lining are also checked.. All lined areas are then spark tested for pinhole leaks using a dielectric spark tester adjusted to 10,000 volts. The tester is moved constantly and quickly over the lining surface to prevent a burn through.
