A method of manufacturing a cable includes at least one elongated electrically conducting element and at least one composite layer surrounding the elongated electrically conducting element. The composite layer is obtained from at least one step of impregnation of a non-woven fibrous material with a geopolymer composition.

Method of manufacturing a fire-resistant and/or fire-retardant cable

The present invention relates to a device comprising a cable and/or a cable accessory, said cable and/or said cable accessory comprising at least one composite layer obtained from a composite composition based on at least one cellulose derivative, at least one organic compound having a boiling point or a decomposition temperature above about 100&#xb0; C. and at least one cement composition selected from an aluminosilicate geopolymer composition and a magnesium-based composition, as well as to a method of manufacturing such a device.

Device comprising a cable or a cable accessory containing a fire-resistant composite layer

The present invention relates to a device comprising a cable and/or a cable accessory, said cable and/or said cable accessory comprising at least one composite layer obtained from a composite composition based on at least one aluminosilicate geopolymer composition and on at least one low-viscosity organic polymer or oligomer, and also to the process for preparing same.

Device comprising a cable or cable accessory containing a fire-resistant composite layer

The present invention relates to a fire-resistant cable comprising at least one electrically insulating composite layer based on at least one cementitious material and at least one starch, and the process for manufacturing same.

Fire-resistant cable

A communications cable has a jacket, a plurality of twisted pairs, each twisted pair having two insulated conductors twisted around one another. A cross-filler is arranged between the twisted pairs where the cross-filler is constructed of PEI (polyetherimide).

LAN cable with PEI cross-filler

A communications cable having a jacket and a plurality of twisted pairs, each twisted pair having two insulated conductors twisted around one another, where on at least one twisted pair, the insulation on the conductors of the pair is a two layer insulation with a first inner layer of polyolefin and a second outer layer of imide polymer.

LAN cable with dual layer PEI/FRPP insulation for primary conductors

A process for the production of a moulding composed of foamed polytetrafluoroethylene by means of an extruder, includes introducing a foaming agent, which brings about foaming, into the polytetrafluoro-ethylene, where the extruder used includes a commercially available extruder, to which a thermoplastically processable, fusible polytetrafluoroethylene is fed, the polytetrafluoroethylene is fed to the extruder together with a foaming agent which has chemical action and which has a decomposition temperature of at least 320&#xb0; C., and after its discharge from the extruder, the moulding is drawn off in the direction of production without any further measures relating to the foaming procedure.

Process for the production of a moulding composed of foamed polytetrafluoroethylene

A foaming composition comprising a melt processible fluoropolymer, and a chemical foaming agent, where the chemical foaming agent is ammonium polyphosphate.

High processing temperature foaming polymer composition

A foaming composition includes a fluoropolymer, a nucleating agent and a pigment, wherein said pigment is a manganese-antimony-titanium (Mn&#x2014;Sb&#x2014;Ti) oxide pigment.
