Evonik Vestodur® GF 20 20% Glass Reinforced PBT (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 20% 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: Glass-bead filled and glass-fiber reinforced compounds with elevated or high rigidity, partially low-warpage; e.g., for housing parts in the automotive industry. Information provided by degussa. Evonik Industries is the successor company to Degussa.
