Teflon® has become an indispensable material for engineers in the chemical processing industry, thanks to these unique properties:
· Excellent chemical resistance
· High temperature resistance
· Low permeation
· High corrosion resistance
ETFE is very tough coating. For instance, it lost only 34µ after 1000 cycles in Taber method. ETFE is the toughest of the fluoropolymers and can be applied at film builds up to 1.000µ to provide a highly durable finish.
ETFE has excellent chemical resistance and can operate continuously at 149ºC/300ºF.
Thermal insulation of Teflon® reduces the temperature gradient, often preventing condensation and subsequent expansion of absorbed fluids. It also reduces the speed and magnitude of temperature changes, minimizing blistering.
ETFE, especially filled ETFE, has low permeation. ( Filled ETFE is 30 times less permeable than unfilled ETFE ).
Because of resistance of TeflonR to the toughest chemicals property, such as acid steam, it increases valve’s economic life.
Moulds coated with Teflon® are used for manufacturing today’s sports shoes. Providing a permanent release surface, Teflon® eliminates aerosol sprays, which contaminate the workplace and cause unwanted rejects.
Fuel filter’s film coated with Teflon® separates water from fuel. Therefore, it prevents going water to the engine.
Paper and Printing:
DuPont industrial coatings are used in the paper industry to improve the efficiency of paper mills, pulp mills and related paper converting industries. In these industries, fibers can stick to process equipment, resulting in expensive downtime for cleaning. In addition, the agglomeration of fibers can often cause quality problems in the finished product. Teflon® increases of roller surface tension providing higher efficiency in ink transfer.
