摘要

Polymer composition containing: as the polymeric constituents A. 90-50 wt. % polybutylene terephthalate (PBT) B. 10-50 wt. % polyethylene terephthalate (PET), the polymeric constituents add up to 100 wt. %, at 100 part by weight of the sum of the polymeric constituents: C. 10-40 part by weight of metal salts of phosphinic acids and/or diphosphinic acids or polymeric derivatives thereof. D. 3-30 part by weight of a nitrogen or nitrogen and phosphor containing flame retardant synergist for metal salts of phosphinic acids and/or diphosphinic acids or polymeric derivatives thereof, E. 0-80 part of glass fibers.
