Anti-corrosion material for electrolytic cells

Anti-corrosion material for electrolytic cellsKeywords: Atofina, Corrosion prevention

Kynar Flex, a high performance fluorinated copolymer from Atofina, has been chosen as an anti-corrosion material for the manufacture of chlorine-soda electrolytic cells using the mercury process.

Kynar Flex claims to offers outstanding resistance to corrosion, excellent chemical stability, remarkable thermal stability (up to 130°C), high purity, and low permeability to chlorine and bases.

Kynar Flex is believed to be very easy to process (sheet extrusion, thermoforming) and to finish (welding, machining, bonding, helical reinforcement), and is thought to be particularly suitable for this type of complex construction when reinforced with a resin and glassfibre hooping.

The first chlorine-soda electrolytic cells using Kynar Flex have been installed at Atofina's Jarrie site (Isére). The properties of this fluorinated copolymer reportedly fulfil the exacting requirements of this application. In addition, thanks to its durability, Kynar Flex claims to offer a very cost-effective solution by reducing maintenance costs.

According to its manufacturers, Kynar Flex is the choice material for chlorine plants as well as for industries using chlorine (paper, pigments, colourants, metal surface treatment, etc.) where solutions need to be found to corrosion-related problems and/or a high level of purity is required.
