Document Type and Number:
WIPO Patent Application WO/2018/050498
Kind Code:
A8
Abstract:
The invention relates to a novel flame retardant-stabilizer combination for thermoplastic polymers, comprising, as component A, from 25 to 99.9 % by weight of a phosphinic acid salt of the formula (I) wherein R1, R2 are the same or different and are each C1-C8-alkyl, linear or branched, C6-C18-aryl, C7-C18-arylalkyl or C7-C18-alkylaryl, or R1 and R2 form one or more rings with each other, M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base; m is from 1 to 4; as component B, from 0 to 75 % by weight of a synergist or of a phosphorus/nitrogen flame retardant and, as component C, from 0.1 to 30 % by weight of telomeric phosphinic acid salts as component D, from 0 to 20 % by weight of organo phosphonic acid salt,, as component E, from 0 to 5 % by weight of phosphonic acid salt, the sum of the components always being 100 % by weight, and wherein the angle of repose of said flame retardant-stabilizer combination is between 5° and 45°.
