The present invention relates to a cable comprising one or more insulated conductors which are embedded in a bedding composition having improved flame retardancy. The bedding composition comprises a resin (A) and inorganic filler (B), which is a hydroxide or hydrated compound.

Cable with improved flame retardancy

The present invention relates to a flame retardant polymer composition comprising (A) an ethylene copolymer comprising alkyl acrylate comonomer units, (B) uncoated aluminum hydroxide as inorganic filler, and (C) an ethylene copolymer comprising maleic anhydride units in an amount of 0.6 to 5 wt. %, an article comprising such a composition, the use of such a composition for producing a layer in a wire or cable and the use of an ethylene copolymer comprising maleic anhydride units for producing a wire or cable fulfilling the requirements of class D of the FIPEC test according to prEN 50399:2007./.

Flame retardant polymer composition comprising an ethylene copolymer with maleic anhydride units as coupling agent

A flame retardant polymer composition comprising (A) an ethylene copolymer comprising polar comonomer units, (B) a silicone-group containing compound, (C) an inorganic filler material, and (D) an ethylene homopolymer or a copolymer of ethylene with one or more other alpha-olefin comonomer units, wherein the polymer composition has a melting enthalpy of at least 78 J/g, an article, in particular a wire or cable, comprising said composition and the use of an ethylene homo- or copolymer in a flame retardant layer of a wire or cable for improving the mechanical properties of the wire or cable.

Flame retardant polymer composition with improved mechanical properties

Certain embodiments of the present technology provide a cable comprising a conductor and a cable layer. The cable layer comprises a polypropylene material. The cable layer and/or the polypropylene material comprise a crystalline fraction crystallizing in the temperature range of 200 to 105&#xb0; C. determined by stepwise isothermal segregation technique. The crystalline fraction comprises a part, wherein, during subsequent melting at a melting rate of 10&#xb0; C./min, the part melts at or below 130&#xb0; C. and the part represents at least 20 percent by weight of the crystalline fraction. In certain embodiments, the part melts at or below the temperature T=Tm&#x2212;3&#xb0; C., wherein Tm is the melting temperature of the cable layer and/or the polypropylene material, and the part represents at least 45 percent by weight of the crystalline fraction. Certain embodiments provide methods and processes for manufacturing the cable described above and herein.
