Abstract
Flame retardant mixtures and the production and use thereof The invention relates to a flame retardant mixture comprising 99.9999% to 87% by weight of diorganylphosphinic salts as component A) and 0.0001% to 13% by weight of iron as component B), where the sum total of A) and B) is 100% by weight; and to processes for preparation thereof and to the use thereof.
Claims28
A flame retardant mixture comprising:
- 99.9999% to 87% by weight of diorganylphosphinic salts as component A);
- and
- 0.0001% to 13% by weight of iron as component B),
- where the sum total of A) and B) is 100% by weight.
A thermoplastic or thermoset polymer molding compound, polymer molding, polymer film, polymer filament or polymer fiber which has been rendered flame-retardant and contains 0.5% to 50% by weight of flame retardant mixtures as claimed in claim 1, 0.5% to 95% by weight of thermoplastic or thermoset polymer or mixtures thereof, 0% to 55% by weight of additives and 0% to 70% by weight of filler or reinforcement materials, where the sum total of the components is 100% by weight and where the polymer comprises thermoplastic polymers of the HI (high-impact) polystyrene, polyphenylene ether, polyamide, polyester or polycarbonate type, and blends or polymer blends of the ABS (acrylonitrile-butadiene-styrene) or PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) or PPE/HIPS (polyphenylene ether/HI polystyrene) polymer type, and/or thermoset polymers of the formaldehyde-, epoxide- or melamine-phenolic resin polymer, unsaturated polyester, epoxy resin and/or polyurethane type.
