Polybutylene Terephthalate (PBT)

Polybutylene Terephthalate (PBT)

PBT Material Properties and Applications 

Polybutylene Terephthalate, or PBT, is a strong synthetic resin produced by the polymerization of butanediol and terephthalic acid. It is known for its strength, dimensional stability, weatherability, colorability and overall durability. PBT resists chemicals and solvents, shrinks little during forming, is mechanically strong and heat resistant and can be treated with flame retardants to make it noncombustible. Its low melting point, excellent flow when molten and rapid crystallization make it attractive for injection molding into solid parts.

Characteristics and Properties
  • Good dimensional stability
  • Ease of flow
  • Good mechanical strength
  • Tensile strength up to 17,000 PSI
  • Excellent chemical resistance
  • Good insulating properties
  • Most grades are filled
  • Agency ratings include UL flammability and RTI
Popular Applications
  • Electrical housings
  • Plug connectors
  • Household appliances
  • Personal care
  • Yarn and other textiles
  • Under-the-hood auto parts
