FLAME RETARDANT SEMI-AROMATIC POLYAMIDE COMPOSITION AND MOULDED PRODUCTS MADE THEREFROM

摘要

The invention relates to a flame retardant polyamide composition comprising (A) a semi-crystalline semi-aromatic polyamide, (B) a semi-crystalline aliphatic polyamide and (C) a halogen free flame retardant system comprising a metal salt of a (di)phosphinic acid, a melamine condensation product, a polyphosphate salt of melamine or a polyphosphate salt of a melamine condensation product, or any mixture thereof; wherein the weight ratio of (A):(B) is in the range of 75:25 -98:2, and (B) has a number average molecular weight (Mn) of more than 7500g/mol. The invention also relates to an article made of the flame retardant polyamide composition.
