Abstract
The invention relates to thermoplastic moulding materials containing A) 10–98 wt. % of at least one thermoplastic polyester, B) 1–30 wt. % of a flame resistant material combination made of 100 wt. % B), b1) 20 99 wt. % of a flame resistant material containing halogen b2) 1–80 wt. % of an antimonoxide, C) 0.01–5 wt. % of tartaric acid or tartrates or a mixture thereof, D) 0 is 5 wt.-% of at least one stabilisator containing phosphorous, E) 0–70 wt.-% of additional materials, whereby the sum of the wt % of the components A)–E) is 100%.
Claims10
A thermoplastic molding composition comprising
- A) from 10 to 98% by weight of at least one thermoplastic polyester
- B) from 1 to 30% by weight of a flame retardant combination made from, based on 100% by weight of B),
- b1) from 20 to 99% by weight of a halogen-containing flame retardant,
- b2) from 1 to 80% by weight of an antimony trioxide or antimony pentoxide
- C) from 0.01 to 5% by weight of tartaric acid or tartrates or mixtures of these
- D) from 0 to 5% by weight of at least one phosphorus-containing stabilizer
- E) from 0 to 70% by weight of one or more other additives selected from the group consisting of esters of saturated and of unsaturated aliphatic carboxylic acids with saturated aliphatic alcohols, amides of saturated and of unsaturated aliphatic carboxylic acids with saturated aliphatic amines, elastomeric polymers, fibrous and particulate fillers, colorants, lubricants, mold release agents, plasticizers and antidrop agents,
- where the total of the percentages by weight of components A) to E) is 100%.
