Abstract

The present invention relates to a flame retardant polyamide composition comprising(a)at least one polyamide;(b)about 8 to 35 wt% of at least one halogen-containing flame retardant;(c)at least one of about 0.3 to 12 wt% basic zinc phosphite represented by the formula xZnO.ZnHPO3, wherein x is a number from 1 / 2 to 10; and optionally(d)up to about 60 wt% of glass fiber, and the total weight percentage of all components included in the composition is 100 weight%.

Description

technical field [0001] The present disclosure relates to flame retardant polyamide compositions comprising a halogen-containing flame retardant and zinc basic phosphite. technical background [0002] Thermoplastic polymers, such as polyesters or polyamides, have excellent mechanical properties, formability and chemical resistance and are therefore used in automotive components, electrical / electronic components and many other applications. In certain applications, it is desirable for these polymers to also be flame retardant. This can be achieved through the incorporation of various additives such as flame retardants. Halogenated organic compounds, such as brominated polystyrene, were previously widely used as flame retardants in the polymer industry. In addition, in order to further synergize or maximize the flame retardancy of halogen-containing flame retardants, metal compound-based synergists (eg, zinc compounds) may be used in combination with these halogen-containing ...
