FIELD: chemistry.SUBSTANCE: invention relates to fire-resistant compositions of polyamide resin. Claimed is a fire-resistant composition of the polyamide resin, including a polyamide (A), which contains a unit, representing diamine and containing not less than 70 mol% of a unit, representing p-xylylenediamine, and a unit, representing dicarboxylic acid and containing not less than 70 mol% of a unit, representing a linear aliphatic dicarboxylic acid, which has from 6 to 18 carbon atoms; an organohalogen compound (B), which serves as fire-protective means; an inorganic compound (C), which serves as auxiliary fire-protective means; and an inorganic filling agent (D), where the polyamide (A) includes a polyamide, which has the concentration of phosphorus atoms, constituting from 50 to 1000 ppm, and a value YI, which by results of differential colorimetric analysis in accordance with JIS-K-7105, does not exceed 10, and the content of the organohalogen compound (B), the content of the inorganic compound (C) and the content of the inorganic filling agent (D) constitutes from 1 to 100 wt.p. from 0.5 to 50 wt.p. and from 0 to 100 wt.p., respectively, counted per 100 wt.p. of the polyamide (A). Also claimed is the moulded product from the said composition.EFFECT: composition has excellent mouldability, mechanical properties, heat resistance and low water absorption.15 cl, 4 tbl, 21 ex |
