Evonik Vestodur® X7085 45% Glass Fiber Reinforced PBT (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 50% Glass Fiber Filled
Material Notes:	Description: VESTODUR X7085 is a 45 % glass fiber-reinforced, polymer-modified polybutylene terephthalate compound for injection molding. The compound is suitable for parts that are subjected to high mechanical and thermal loads. Compared with commonly used glass fiber-reinforced PBT compounds with similar stiffness parts of VESTODUR X7085 have in particular a high surface quality. Information provided by degussa. Evonik Industries is the successor company to Degussa.
