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

摘要

The present invention provides a composition comprising (A) semi-crystalline semi-aromatic polyamide; (B) semi-crystalline aliphatic polyamides; And (C) a halogen-free flame retardant system comprising a metal salt of (di) phosphinic acid, a melamine condensation product, a polyphosphate salt of melamine, a polyphosphate salt of melamine condensation product, or any mixture thereof. The flame retardant polyamide composition has a weight ratio of A) :( B) of 75:25 to 98: 2 and the number average molecular weight (Mn) of (B) is more than 7,500 g / mol. The present invention also relates to a product composed of the flame retardant polyamide composition.
