Arkema launches new renewable PVDF range from crude tall oil

Arkema has launched its new sustainable Kynar PVDF vary. These new grades will declare 100% renewable attributed carbon derived from crude tall oil (CTO) bio-feedstock, in keeping with a mass-balance strategy.

Kynar CTO PVDF grades utilizing the mass steadiness strategy below the ISCC+ certification course of might be produced first in Arkema’s Pierre-Bénite plant in France for its European prospects, focusing initially on grades particularly focused for the lithium-ion battery market.

Kynar CTO grades might be provided as functionally equivalent alternate options to Arkema’s flagship binder grades, Kynar HSV900 and Kynar HSV1810.

This patent-pending expertise permits a local weather change affect discount of just about 20% of the Kynar PVDF binder (expressed in kg eq. CO2/kg, in keeping with the ISO14040 customary) whereas lowering dependence on upstream crude oil consumption. The crude tall oil utilized in upstream feedstock manufacturing is a residue of the Kraft technique of wooden pulp manufacture.

The brand new Kynar CTO grades are licensed to be compliant with accountable forestry requirements. They don’t lead to deforestation, and there’s no direct competitors with meals crops.

Arkema has been a pacesetter in superior bio-circular polymers for a few years. Now, we’re taking an enormous step ahead to make fluoropolymer grades utilizing bio-sourced carbon solely. It’s a exceptional innovation that we proudly share with our prospects the world over. There’s a actual demand for extra sustainable options and we’re glad to play a number one function.

In a second section, the manufacturing of this vary of sustainable PVDF grades might be prolonged to every of Arkema’s international PVDF manufacturing websites and might be made out there to all conventional PVDF markets and purposes.

Moreover, Arkema has already introduced a venture in the US to supply PVDF grades utilizing fluorine derived as a co-product from the agrochemical business, thus requiring no devoted fluorspar mining. These grades are anticipated to be commercialized by mid-2022.

PVDF is the second largest fluoropolymer sector after polytetrafluoroethylene (PTFE) and is used as a binder within the manufacturing of electrodes for lithium-ion and lithium metallic polymer batteries and as a separator coating. The sector has benefitted from robust progress in electrical car (EV) demand, notes market intelligence agency Roskill.

World manufacturing capability for PVDF is dominated by China. Main international producers embody Arkema and Solvay, which each have services in China, Europe and the US.
