Abstract: The invention pertains to certain perfluorinated thermoplastic elastomers suitable for being processed through additive manufacturing techniques, thanks to their surprising ability to possess better processability (notably more significant shear thinning at processability temperature) than corresponding perfluorinated thermoplasts, which possess similar product profile and hence performances, offering hence advantages in throughput and part design accurate control, containment of degradation, reduction of fumes, and yet delivering parts with outstanding chemical resistance.
