Degussa AG Vestodur® GK 20 20% Glass Bead Reinforced PBT

Subcategory: Polyester, TP; Polybutylene Terephthalate (PBT); Thermoplastic; Polymer

Material Notes:
Description: VESTODUR GK20 is a 20% glass beads-filled, semicrystalline thermoplastic polyester compound based on polybutylene terephthalate (PBT).The compound is suitable for injection molding mechanically and thermally highly stressed parts with good surface quality. Compared to unfilled PBT compounds VESTODUR GK20 shows a higher stiffness, a reduced, almost isotropic mold shrinkage, and thus a lower tendency to warp.
