AKU®-LYTE PBT ROUND BARS or FULL BARS

PBT belongs to the group of partially crystalline thermoplastic saturated polyesters based on polybutylene terephthalate and are used as materials for high-quality and heavy-duty parts in many industrial sectors.
PBT is characterized by high stiffness and strength, very good dimensional stability in heat, low water absorption and good resistance to many chemicals.
In addition, PBT exhibits excellent weather resistance and outstanding heat aging behavior.

  • Extremely high toughness and screw pull-out strength down to -60°C
  • hard, stiff, firm
  • Good sliding properties
  • High dimensional stability
  • Can be painted and metallized
  • Continuous operating temperature approx. +100°C to -60°C
  • Good UV and weather resistance

Rods made e.g. from Ultradur®

Polybutylene terephthalate
PBT for short, is a thermoplastic high-performance plastic that belongs to the polyesters.
It is produced by the polycondensation of terephthalic acid or dimethyl terephthalate with 1,4-butanediol.

Properties of PBT:

  • Good mechanical properties:
    PBT has good mechanical properties, including high tensile strength and balanced stiffness, making it suitable for structural applications.

  • Good dimensional stability:
    PBT retains its shape and dimensions well even at varying temperatures, making it suitable for applications with tight tolerances.

  • Good chemical resistance:
    PBT is resistant to many chemicals, making it attractive for various industrial environments.

  • Electrical insulation:
    Due to its good dielectric properties, PBT is often used in electrical applications, such as for housings of electronic components.

  • Low water absorption:
    PBT absorbs only small amounts of water, which leads to stable mechanical properties, even under humid conditions.

  • Good surface finish:
    PBT can have a smooth surface and is therefore well suited for applications where an appealing aesthetic is required.

Applications of PBT:

PBT is used in a wide range of applications in various industries, including:

  • Automotive industry:
    Parts such as bumpers, door handles, switch housings and other components in the vehicle interior and exterior.

  • Electronics industry:
    Housings for electrical and electronic devices, connectors, switches and other components.

  • Household appliances:
    Parts for household appliances such as washing machines, dishwashers, and power tools.

  • Textile industry:
    PBT fibers can be used in textiles to improve certain properties such as dimensional stability and wrinkle resistance.

  • Industrial applications:
    Various technical parts, housings, and components where a combination of mechanical properties is required.

PBT is widely used in many areas due to its versatility and good combination of mechanical, thermal and electrical properties.
