Arkema launches new renewable PVDF range from crude tall oil for Li-ion batteries

Green Car Congress

These new grades will claim 100% renewable attributed carbon derived from crude tall oil (CTO) bio-feedstock, according to a mass-balance approach. Arkema has been a leader in advanced bio-circular polymers for many years. Now, we are taking a huge step forward to make fluoropolymer grades using bio-sourced carbon only.
