An insulated conductor including: at least one electrical conductor; and, an insulating coating covering said electrical conductor, having n layer(s), 'n' being an integer greater than or equal to 1, the nlayer being the outermost layer having a pseudo-amorphous composition Cincluding at least 50% by weight of a polyaryletherketone. A process for manufacturing the insulated conductor, a heat-welding process using two sections of insulated conductor, and a coil capable of being obtained by heat-welding a winding of the insulated conductor.

Insulated conductor for use in a winding, winding derived therefrom and corresponding manufacturing methods

A polymer blend, including: (i) a poly(aryl ether ketone); (ii) a polysiloxane; and (iii) a block copolymer containing polysiloxane blocks. A process for manufacturing the polymer blend, the use of the polymer blend for the manufacture of parts, notably in the petroleum, cabling, aeronautical, motor vehicle, electronics, electrotechnical, composite, additive manufacturing and medical device sectors and also a part at least partially manufactured from said blend.

Blends of polyaryletherketones having improved impact-resistance, elongation at break and flexibility

The use of PEKK for lowering the COand HS permeability of a part intended to enter into contact with a petroleum effluent. Also, a pipe for transporting a petroleum effluent, including a layer intended to be in contact with the petroleum effluent, wherein the layer intended to be in contact with the petroleum effluent comprises PEKK and has a COpermeability at 130&#xb0; C. of less than 10cm, for a thickness of 1 cm and a surface area of 1 cmand per second and bar of COpressure and/or an HS permeability at 130&#xb0; C. of less than 10cmfor a thickness of 1 cm and a surface area of 1 cmand per second and bar of HS pressure, the amount of COand HS being measured by GC, respectively. Lastly, a number of methods for manufacturing such a pipe.
