Easy-flow, glass fiber-reinforced polybutylene terephthalate compound with increased impact strength 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 fiberreinforced PBT compounds with a similar stiffness VESTODUR X4877 has an increased impact strength and also a higher strain at break. |
