PBT — Polybutylene Terephthalate
PBT is an engineering polyester with good dimensional stability, good electrical properties and good chemical resistance.
What is PBT?
PBT is an engineering polyester with good dimensional stability, good electrical properties and good chemical resistance.
Typical properties
| Density | ~1.30–1.32 g/cm³ |
| Tensile strength | ~45–65 MPa |
| Melting point | ~220–230 °C |
| Electrical insulation | good |
