Abstract: The invention pertains to a framing structure for a solar panel made from a polymer composition (C) comprising at least one polyamide polymer [polyamide (A)], and at least one reinforcing filler [filler (F)], the framing structure being characterized by having a top surface and a bottom surface, said top surface having a depressed central portion sized for receiving a solar panel. It also relates to a method for manufacturing the same, to a method for assembly a solar panel into said framing structure, to a solar panel assembly comprising the same, and to a method for fixing said solar panel assembly onto a support (e.g. a roof).

Abstract: A process for transferring heat comprising the following steps: (1) transferring heat from a body to a first heat transfer system by means of a secondary loop passageway comprising a heat transfer fluid and, optionally, (2) transferring heat from a second heat transfer system to said body by means of said secondary loop passageway comprising said heat transfer fluid, wherein: said second heat transfer system being the same as or different from said first heat transfer system, said secondary loop passageway comprises at least one polymer sealant selected from a rubber seal and a plastic pipe; and said heat transfer fluid comprises one or more linear perfluoropolyethers having formula RF—(OCF2)n(OCF2CF2)m(OCF2(CF2)zCF2)p—ORF (I), wherein RF, equal or different at each occurrence, is a C1-C3 perfluoroalkyl group, m, n and p, equal to or different from each other, are integers comprised between 0 and 100, the sum m+n being higher than 0, and z is equal to 1 or 2, and wherein said heat transfer fluid is circulat

Abstract: A method of forming a lubricating film on a surface, comprising applying to a surface a multiphasic composition comprising at least one (per)fluoropolyether (PFPE) lubricant, water and from 0.1 to 3% by weight of water of at least one thickening agent, said multiphasic composition having a viscosity, when measured at 21° C. at a shear rate of 1 sec?1 of at least 10 Pa×sec so as to form a layer, and drying said layer to form a lubricating film. The Applicant has found that by the use of the multiphasic composition as above detailed it is advantageously possible to convey to surface to be lubricated the PFPE lubricant by using application techniques (doctor blade, metering rod, . . . ) as those suitable for solid-like greases, while the actual conveyed lubricant behaves in lubrication as an oil, avoiding the use of fluorinated solvents.

Abstract: The invention pertains to a drilling fluid composition comprising:—at least one (per)fluoropolyether oil comprising recurring units of formula —CF(CF3)CF2O— said oil having a kinematic viscosity of 30 to 80 cSt measured according to ASTM D455 standard at 20° C. [oil (E)] and possessing a polydispersity index (PDI) of at least 1.15; and—at least one (per)fluoropolyether phosphate comprising at least one perfluoropolyoxyalkylenic chain and at least one phosphoric acid group, in its acid, amide, salt or ester form [phosphate (P)], to a method for its manufacture and to its use in a drilling rig equipment.
