Evonik Vestodur® X4877 30% Glass Reinforced PBT
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 30% Glass Fiber Filled
Material Notes:	Description: VESTODUR X4877 is an easy-flow, glass fiber reinforced (30 %) polybutylene terephthalate compound (PBT) with increased impact strength for injection molding. This compound is especially suitable for the manufacture of parts which are subjected to high mechanical and thermal loads. Compared with commonly used glass fiber reinforced PBT compounds with a similar stiffness VESTODUR X4877 has an increased impact strength and also a higher strain at break. Information provided by degussa. Evonik Industries is the successor company to Degussa.
