The invention relates to a halogen-free, flame retarder composition for use in a thermoplastic composition, in particular a glassfibre-reinforced polyamide composition, which flame retarder composition contains at least 10-90 mass % phosphinate compound according to formula (I) and/or formula (II) and/or polymers thereof and 90-10 mass % polyphosphate salt of a 1,3,5-triazine compound according to formula (III) and 0-30 mass % olefin copolymer. When used as a flame retarder in glassfibre-reinforced compositions the halogen-free flame retardant composition results in a combination of a V-0 rating according to the UL 94 test of Underwriters Laboratories and excellent mechanical properties. The invention therefore also relates to the use of this flame retarder composition as a flame retarder in a polyamide composition, and a flame retardant polyamide composition that contains the flame retarder composition. The invention also relates to a moulded article containing the flame retardant polyamide composition, and the use thereof in the field of electrical and electronic applications.

Halogen-free flame retarder composition and flame retardant polyamide composition

The invention relates to a polyamide composition for the production of electrical and electronic components that are suitable for the conditions of the surface mounting technology. In particular, the composition exhibits a high resistance to blistering during the reflow soldering process. The composition according to the invention comprises (a) a polyamide having a melting point higher than 280&deg; C., (b) a polymer having a melting point lower than 230&deg; C., (c) a halogen-containing compound, (d) optionally a synergist for the flame-retardant properties (e) reinforcing material (f) optionally other additives. A particularly good resistance to blistering is achieved if (f) contains at least a compound with acid imide groups.

High-melting polyamide composition for electronic applications

Flame retardant polyamide composition

Car part made from a polyamide composition wherein the polyamide substantially consists of 60-99 wt. % units derived from aliphatic dicarboxylic acids and diamines and the remaining chain units are derived from cycloaliphatic dicarboxylic acid(s) and an aliphatic diamine or cycloaliphatic diamine(s) and an aliphatic dicarboxylic acid.

Car parts made from a polyamide composition

The invention relates to a flame retardant polyamide composition comprising at least one polyamide and a polymerized bromostyrene. In particular, the invention relates to polyamide compositions comprising a polymerized bromostyrene with a bromine content of more than 61% (wt).
