Product Name:Polybutylene terephthalate (PBT)
English Name:Polybutylene terephthalate (PBT)
CAS No.:26062-94-2
Aliases:Polybutylene terephthalate resin, PBT resin, Polytetramethylene terephthalate
Molecular Formula:(C12H12O4)n
Physical Properties:Off-white or light yellow semi-crystalline thermoplastic polyester, density approx. 1.31-1.38 g/cm³, melting point 225-235°C, crystallinity up to 40%. Low melt viscosity and good flowability, water absorption 0.10%-0.25%, susceptible to hydrolysis at high temperature, requiring pre-drying before molding.
Uses:Used in electronic appliances, automotive parts, machinery, household goods, etc., and is one of the five major engineering plastics. Wire-drawing grade PBT is suitable for extrusion and wire-drawing processes, offering excellent mechanical properties, chemical resistance, and electrical insulation.
Technical Specifications:
Melting point: 225-235°C
Density: 1.31-1.38 g/cm³
Water absorption: 0.10%-0.25%, dry to below 0.02% before molding
Crystallinity: up to 40%
Mold shrinkage: 1.7%-2.3%
