    Abstract: Flame-retardant mixtures containing: a) salt of phosphinic acid of formula (I), wherein R1 and R2 mean, independently of each other, alkyl-, cycloalkyl-, aryl- or aralkyl, substituted as applicable, M is m-valent cation, and m means 1 to 4, b) salt of phosphinic acid of formula (II), differing from component a), wherein R3 means substituted, as applicable, alkyl-, cycloalkyl-, cycloalkyl-alkyl, aryl- or aralkyl, preferably with alkyl radicals as substituents, R4 is alkyl having even number of carbon atoms (if R1 and/or R2 are alkyl, R4 has double, triple or quadruple the number of carbon atoms of R1 or R2), M is n-valent cation and n means 1 to 4, c) organylphosphonate, d) phosphite, e) as applicable, a representative selected from the group consisting of triazine complex, polyphosphate, hypophosphite, nitrogenous diphosphate, organophosphate, phosphazene and/or polyphosphonate, f) as applicable, a representative selected from the group consisting of metal hydroxide, metal carbonate, metal borate, zinc stannate and/or intumescence additive, and g) as applicable, pigment, wherein at least one of components e) and/or f) must be present in the mixture. The mixtures can use thermoplastic and elastomeric polymers to produce flame-retardant polymer compositions, which are exceptionally suitable for producing cable sheathing or cable insulation.

    Abstract: Flame retardant mixtures, flame-retardant polymer compositions, cables endowed therewith and use thereof What are described are flame retardant mixtures comprising a) salt of a phosphinic acid of the formula (I) in which R1 and R2 are independently alkyl, cycloalkyl, aryl or aralkyl that are optionally substituted, M is an m-valent cation, and m is 1 to 4, b) salt of a phosphinic acid of the formula (II) that differs from component a) in which R3 is optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, aryl or aralkyl, preferably with alkyl radicals as substituents, R4 is alkyl with an even number of carbon atoms, with the proviso that, if R1 and/or R2 are alkyl, R4 has twice, three times or four times the number of carbon atoms of R1 or R2, M is an n-valent cation, and n is 1 to 4, c) organylphosphonate, d) phosphite, e) silicate, alumosilicate and/or silicon dioxide which is solid at 25° C., f) a representative selected from the group of triazine complex, polyphosphate, hypophosphite, nitrogen-containing diphosphate, organophosphate, phosphazene and/or polyphosphonate, g) optionally a representative selected from the group of metal hydroxide, metal carbonate, metal borate, zinc stannate and/or intumescent additive, and h) optionally pigment. The mixtures can be used for production of flame-retardant polymer compositions comprising thermoplastic and elastomeric polymers that are of excellent suitability for production of cable sheaths or cable insulations.

    Abstract: A halogen-free flame retardant mixture containing between 1-99 wt. % of a component A and between 1-99 wt. % of a component B. Component A comprises between 85-99.995 wt.-% of a solid diethylphosphinic acid salt of the metals Mg, Ca, Al, Sb, SN, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base and between 0.005-15 wt.-% of non-combustible additives and component B is in the form of an aluminum phosphite.

    Abstract: Sustainably produced dialkylphosphinic salts The invention provides a process for producing dialkylphosphinic salts of the formula (I),






    in which
    a and b may be the same or different and are each independently 1 to 9, and where the carbon chains may be linear, branched or cyclic, and
    M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base and
    m is 1 to 4,
    characterized in that the process comprises:
    feeding a substream of renewable raw materials and/or recycled raw materials into a main stream of conventional raw materials originated from petroleum;
    converting said renewable raw material and/or recycled raw materials to ethylene together with said conventional raw materials;
    reacting the resultant ethylene stream with derivatives of hypophosphorous acid to give a derivative of the dialkylphosphinic acid; and
    reacting said derivative of the dialkylphosphinic acid with a metal salt to give dialkylphosphinic salts of the formula (I),
    wherein the renewable raw materials are tall oil, tung oil, wood tar, creosote, or vegetable oils such as palm oil, soya oil, rapeseed oil, sunflower oil, palm kernel oil, cottonseed oil, peanut oil, maize kernel oil, coconut oil, olive oil, sesame oil, linseed oil and/or safflower oil,
    wherein said recycled raw materials are selected from food wastes, residues or wastes from food production, papermaking or pulp processing, and any other materials of recycled origin, and the ratio of said mainstream of conventional raw material to said substream of renewable raw materials and/or recycled raw materials is 109:1 to 1:106.
