Abstract
The present invention relates to a flame retardant resin composition comprising: 100 parts by weight of a thermoplastic polyamide resin (A), 1 to 100 parts by weight of a phosphazene compound (C), and a polyphenylene ether-based resin, a polystyrene-based resin or mixture thereof (B) being present in an amount of 10 to 500% by weight based on the weight of said phosphazene compound (C).
Claims18
A flame retardant resin composition comprising:
- 100 parts by weight of a thermoplastic polyamide resin (A),
- 1 to 100 parts by weight of a phosphazene compound (C), and
- a phosphazene compatibility enhancing resin (B), consisting essentially of a polyphenylene ether-based resin, or a mixture of a polyphenylene ether-based resin and a polystyrene based resin being present in an amount of 10 to 500% by weight based on the weight of said phosphazene compound (C);
- wherein the phosphazene compatibility enhancing resin (B) is present in an amount sufficient to prevent bleed-out of the phosphazene compound.

A flame retardant resin composition comprising:
- 100 parts by weight of a thermoplastic polyamide resin (A),
- 1 to 100 parts by weight of a phosphazene compound (C), and
- an anti-bleedout resin (B) comprising a polyphenylene ether-based resin, a polystyrene-based resin or mixture thereof, the anti-bleedout resin being present in an amount of 10 to 500% by weight based on the weight of said phosphazene compound (C), and the anti-bleedout resin (B) is present in an amount sufficient to prevent bleed-out of the phosphazene compound,
- resin pellets comprising said flame retardant resin composition being producible by extruding of said flame retardant resin composition by using a twin-screw extruder at 270° C. without bleed-out of phosphazene compound (C).
