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.

Abstract: The present invention relates to a method for manufacturing semiconductor devices, including a step wherein a semi-conductor device exchanges heat with a heat transfer fluid. The heat transfer fluid comprises one or more chemical compounds having the general formula: Ph(ORf)x (I) wherein Ph is an aromatic ring linked to one or more ether groups —ORf where each —Rf: — is a monovalent fluorinated alkyl group comprising at least one C—F bond, — has a carbon chain, preferably a C1-C10 carbon chain, which can be linear or can comprise branches and/or cycles, and, optionally, can comprise in chain heteroatoms selected from O, N or S, and wherein, when X>1, the —Rf groups on the same molecule can be equal to or different from each other.
