Arkema wins Pierre Potier 2016 prize
Arkema has recently won the Pierre Potier 2016 prize for its latest Kynar® fluoropolymer grade with durable hydrophilic properties. This innovative material makes it possible to produce latest generation hollow fibers, more efficient and less energy intensive, specifically intended for the manufacture of ultrafiltration modules for water purification.

Access to drinking water is a major global issue, and, from its creation, Arkema made water management one of its six research and development platforms.

The innovative solution developed by Arkema which has won this award entails the development of a new fluoropolymer grade with lasting hydrophilic properties. The fruit of six years’ research and innovation at Arkema’s Lacq research center, this new material makes it possible to manufacture latest generation hollow fibers used in ultrafiltration modules.

The membrane filtration technology is widely used in water treatment and wastewater recycling; the water is fed under pressure through long hollow fibers that retain suspended solids, impurities and bacteria.

Developed in partnership with Polymem, a French manufacturer of modules for water filtration, this latest material, by combining the outstanding properties of Kynar® PVDF with a sustainable hydrophilic characteristic, provides an effective and innovative solution to the needs of the market in terms of membrane performance and energy consumption.

While maintaining the quality of filtration for suspended solids, bacteria and viruses, it ensures a 20% increase in the volume of treated water – for constant energy consumption – while also significantly extending the service life of the filtration systems from 5 to 10 years.

This latest membrane solution is already being marketed and undergoing full-scale testing in a municipal water treatment plant in Toulouse to meet the many water purification needs of communities, industries and households.

This innovation draws on controlled radical polymerization, a unique technology developed by Arkema’s R&D which ensures a perfectly controlled arrangement of the polymer’s various molecules on a nanometric scale. It is thanks to this technology, called BlocBuilder®, that this new material combines hydrophilic properties with the outstanding mechanical strength and chemical stability of Kynar® PVDF.
