Реферат: Thermoplastic molding composition comprises (wt.%): (A) thermoplastic polyester (20-97); (B) phosphinic acid and/or diphosphinic acid salt (1-40), with mean particle size (d50-value) of less than 10 micro m; (C) nitrogen containing fire protection agent (1-30); (D) at least one ester or amide of an (un)saturated 22-40C carboxylic acid, with aliphatic saturated 2-40C alcohols or amines; and (E) other additives (0-60), is new. Independent claims are included for: (1) process for preparation of the molding composition by mixing components B and C, mixing with component A and optionally component D and/or component E, homogenization of the melt, discharge, cooling and granulation; and (2) shaped part obtained from the molding composition.
Flameproof thermoplastic molding material, e.g. for electrical plugs and lamp parts, contains polyester, halogenated fire retardant, antimony oxide, calcium phosphonate or aluminum phosphinate and anti-drip additive
