Product Name:PBT LW9020
English Name:PBT LW9020
CAS No.:26062-94-2
Aliases:Polybutylene terephthalate, PBT resin, Poly(1,4-butylene terephthalate)
Molecular Formula:(C12H12O4)n
Physical Properties:PBT is a crystalline thermoplastic polyester with a density of about 1.31 g/cm³, low water absorption (about 0.07%~0.1%), and a melting point of approximately 225°C. It exhibits excellent mechanical strength, fatigue resistance, dimensional stability, and heat aging resistance (enhanced grades achieve a UL temperature index of 120~140°C). The electrical insulation is outstanding, with a dielectric constant of 3.0~3.2 and arc resistance of 120s. It has good solvent resistance and is free from stress cracking, but is sensitive to water and prone to hydrolysis under high temperature and high humidity.
Uses:Widely used in electronic and electrical applications, such as connectors, switch parts, household appliance components, and coil bobbins. It is also used in automotive exterior parts (corner grilles, radiator vent covers), interior parts (mirror supports, wiper brackets), and automotive electrical parts (ignition coil tubes, connectors). Additionally, it is utilized in machinery for gears, cams, buttons, electronic watch cases, and camera components.
Technical Specifications:
Density: approximately 1.31 g/cm³; low water absorption (0.07%~0.1%)
Melting point: approximately 225°C; fast crystallization and good flowability
Dielectric constant: 3.0~3.2; arc resistance: 120s
UL temperature index of enhanced grades: 120~140°C
Suitable for injection molding or extrusion on conventional equipment
