Product Name:Polybutylene terephthalate (PBT)
English Name:Polybutylene terephthalate (PBT)
CAS No.:26062-94-2
Aliases:PBT, Poly(butylene terephthalate), Poly(tetramethylene terephthalate)
Molecular Formula:(C12H12O4)n
Physical Properties:Polybutylene terephthalate (PBT) is a linear saturated polyester produced by polycondensation of terephthalic acid and 1,4-butanediol. Density is 1.41 g/cm³, moisture absorption (equilibrium 50% RH) 0.17%, saturation water absorption 0.42%; melting point (DSC) 225℃, heat deflection temperatures are 220℃/195℃/83℃ at 0.45 MPa/1.80 MPa/8.00 MPa, Vicat softening temperatures 221℃/205℃ (10 N/50 N); thermal conductivity 0.26 W/(m·K), limited oxygen index 19%. Excellent electrical properties: surface resistance 1×10^15 Ω, relative permittivity 4.1 (100 Hz) and 3.5 (1 MHz), electric strength 27 kV/mm (1 mm thickness).
Uses:Glass-fiber reinforced PBT offers excellent mechanical properties, heat resistance, electrical insulation and dimensional stability. It is widely used in electronic and electrical components (connectors, relays, switches, coil bobbins), automotive parts (sensor housings, lamp components, ignition parts) and mechanical parts. The 15% glass-fiber reinforced grade provides improved stiffness, creep resistance and dimensional accuracy compared with unreinforced PBT.
