摘要： A flame-retardant cable (10;20;30;40;50) having at least one core (31;41;51) comprising a conductor (11), and at least one protecting layer (13a; 13b; 14; 15; 47) surrounding the cable core (31;41;51), wherein the protecting layer (13a; 13b; 14; 15; 47) is made from a low smoke zero halogen (LS0H) flame-retardant polymer composition comprising at least 70 phr of a polyethylene homopolymer or copolymer having a density lower than 0.90 g/cm 3 as halogen-free polymeric base added with
a) from 100 to 800 phr of at least one metal hydroxide; and
b) at least 10 phr of a tannin.
The cable has improved reaction to fire performances, in particular a reduced or null dripping under fire, which render it compliant with the requirements of the more recent international standards.-

摘要： A flame-retardant electric cable (10;20) having a core comprising at least one electric conductor (11), an electrically insulating coating (12) and an outermost layer (13a;14) made from a substantially thermoplastic, low smoke zero halogen flame-retardant polymer composition comprising:
a) a polymeric base made of at least one polyethylene homopolymer or copolymer having a density of 0.94 g/cm 3 at most;
b) 60-64% by weight of a metal hydroxide;
c) at least 2% by weight of an ammonium coated montmorillonite having average particle dimensions of from 5 to 20 µm; and
d) a polysiloxane.
Such a cable has improved reaction to fire performances, especially reduced dripping or absence of dripping during burning, which render it compliant with the requirements of the more recent international standards.-

摘要： A flame-retardant electric cable (10) is disclosed, the cable (10) having a core comprising an electric conductor (11) and an electrically insulating layer (12) comprising a flame-retardant polyolefin-based composition comprising:
a) as base polymer, a mixture of at least two polyolefin homopolymers and/or copolymer wherein at least one is a low-density polyethylene copolymer having a density lower than 0.915 g/cm3;
b) calcinated kaolin in an amount greater than 3 phr;
c) a metal hydroxide in an amount greater than 10 phr; and
d) an alkyl or alkenyl alkoxy siloxane,
wherein the alkyl or alkenyl alkoxy siloxane is in an amount ratio of from 1:25 to 1:50 with respect to the sum of the amounts of calcinated kaolin and of the metal hydroxide.-

摘要： A cable for applications which entails heavy mechanical stresses and/or harsh environmental conditions comprises at least one core (2) having at least one transmissive element (3) and an outer sheath (5) disposed in radially external position with respect to the core (2) . The outer sheath (5) comprises a reinforcing layer (6) comprising a fibril reinforced polymeric matrix. A process for manufacturing such a cable comprises the steps of providing a core (2) having at least a transmissive element (3) , providing a first compound of fibrils and a matrix and applying the first compound around the core (2) to form the reinforcing layer (6) comprising the fibril reinforced polymeric matrix. The invention deals also with the use of fibrils for the manufacturing of a coating layer for a cable.
