Abstract

Polymeric composition based on a PVDF homopolymer and a thermoplastic fluorocopolymer Polymeric composition based on a PVDF homopolymer and a thermoplastic fluoropolymer offering an improved toughness/processability compromise, possessing an apparent melt viscosity not exceeding 60 000 Pa·s at a shear rate of 1 s−1, a ductile-brittle transition temperature below +5° C. and a weight loss in air at 150° C. of 5% or less. Pipes and fashioned articles prepared from this composition.
