Evonik Vestodur® GF30-FR3 30% Glass Reinforced, Self Extinguishing PBT
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 30% Glass Fiber Filled
Material Notes:	Description: Degussa AG’s High Performance Polymers Business Unit manufactures a range of polybutylene terephthalate compounds that are supplied under the registered trademark VESTODUR® . Material properties characterizing VESTODUR compounds are: high thermostability high stiffness low water absorption resulting in high dimensional stability high hardness good strength good sliding friction behavior, low abrasion good creep behavior good electrical properties good chemical resistance good weathering resistance good processability no tendency to form stress cracks Specific Notes for this Material: Compounds made self-extinguishing with non-migrating flame retardants, reinforced and unreinforced, for use in electrical applications in particular. The compounds are listed by UL (Underwriters Laboratories), partially down to 0.4 mm wall thickness or with addition of up to 50 wt.-% regrind. Information provided by degussa. Evonik Industries is the successor company to Degussa.
