The present invention relates to a shielding system for conductor cables as well as to a method for producing said shielding system. The system is characterized in that it comprises a corrugated tube () coated with one or more thin films of high electrical conductivity material () which are reversibly adhered to the surface of said corrugated tube () so that said coating can be uncoupled from the corrugated tube due to high bending values of the tube itself. The shielding system according to the present invention therefore combines the excellent shielding efficacy values of a system having thin metal films with the excellent flexibility properties of a corrugated plastic tube.

Flexible, total coverage electromagnetic wave shielding system

Gasket for refrigerator cabinets for providing seal-tight closure between cabinet () and door () composed of an outer door () and inner door (), comprising a soft bellows portion (), characterized in that said soft bellows portion () is interposed in an extensible manner between at least a pair of magnets () one of which is operatively coupled to said door and the other is coupled to said cabinet.

Magnetic gasket for refrigerator cabinets

Gasket for refrigerator cabinets of the kind including a soft bellows-type portion used for sealing the area between the cabinet and the door and extending from a base portion able to match the outer door and/or inner door of the refrigerator cabinet. The base portion is substantially rigid and has at one end, a sealing portion made of substantially soft material extending toward the inner door. The soft material portion has good flexible and spring back features when exposed to refrigerator and freezer temperatures. These features make the gasket able to further seal, preferably by compression, the space located between the cabinet and inner door in a more internal area of the refrigerator cabinet. Furthermore, the soft sealing portion is independent and free from constraints with respect to the soft bellows-type portion.

Fluorinated polyesters

A non-fluorinated epoxy prepolymer of known type is mixed with a fluorinated epoxy prepolymer containing perfluoropolyether blocks or perfluoroalkylene blocks of type --(CF.sub.2 CF.sub.2).sub.n -- and/or of type ##STR1## and the two prepolymers are co-cured by treating the mixture with cross-linking agents of known type suitable for epoxy resins, thereby obtaining a cross-linked epoxy resin having a fluorine content.ltoreq.30% by weight, preferably.ltoreq.25% by weight.

Epoxy resins prepared by co-curing fluorinated epoxy prepolymers and

Fluorinated polyisocyanates particularly suitable for the formulation of coating paints and compositions in the electronics industry, obtained by starting from a perfluoropolyether polyol having a functionality higher than 2 and from a diisocyanate, the resulting derivative having isocyanic functions being further condensed with a polyol in order to obtain a polyisocyanate with a high degree of functionality, and containing from 1.5% to 9% by weight of --NCO groups.

Fluorinated polyisocyanates suitable as paint components

Non-fluorinated tertiary aminic compounds, comprising two or more functional groups containing at least three active H, of the hydroxyl or aminic or thiol type, are utilized, in the form of a homogeneous mixture with perfluoropolyethers having hydroxy end groups, to prepare by means of polycondensation and cross-linking reaction with fluorinated or non-fluorinated polyisocyanates, carried out in the absence of catalysts, the corresponding polymers containing the perfluoropolyethereal chain deriving from the perfluoropolyether having hydroxy end groups.
