Melting point: 54-56 °C: Boiling point: 300 °C: Density : 0.92 g/mL at 25 °C (lit.) refractive index : n 20/D 1.51: form : … WebFast crystallization rate enhances moldability, producing smooth surfaces that can be painted, printed, and ultrasonically welded. UL temperature indexes are relatively high because of a 227C (440F) melting point and a 40C (104F) glass-transition temperature. Unreinforced PBT has a heat-deflection temperature of 154C (310F) at 66 psi (0.5 MPa).
