Polybutylene terephthalate (PBT)
Description (definition)
Polybutylene terephthalate (PBT) is a thermoplastic material from the polyester group that is characterized by high strength, rigidity, heat resistance and good electrical insulation properties. PBT is resistant to chemicals, moisture and has low friction, making it frequently used in the automotive, electronics and household appliance industries.
Example
A well-known example of PBT is the production of connectors and housings in the automotive industry. Thanks to its insulating properties and resistance to high temperatures, PBT ensures reliable electrical connections in vehicles.
What are the main advantages of PBT?
PBT offers a combination of strength, heat resistance and excellent electrical insulation properties. It is resistant to chemicals, UV radiation and moisture, making it ideal for use in demanding environments. PBT is also easy to process and enables the production of precise components.
Where is polybutylene terephthalate typically used?
PBT is widely used in the automotive industry for connectors, sensor housings and switches. In electronics, it is used for cable sheathing and housings, while it is used in household appliances such as coffee machines and hair dryers due to its heat resistance.
How is PBT processed?
PBT is usually processed by injection molding or extrusion. Thanks to its thermoplastic properties, it is easy to mold and is suitable for complex, thin-walled components. During processing, PBT can be reinforced with glass fibers or other fillers to provide additional stability.
