What is PBT?
PBT (polybutylene terephthalate) is a semi-crystalline engineering thermoplastic from the polyester family.
The material is dimensionally stable and a good electrical insulator, and is frequently tailored to demanding components with glass fibres or additives.

Where is PBT used?
PBT is used above all in electrical and electronic components, for instance in connectors, switches, housings, and coil formers.
In vehicle engineering, PBT matters for under-bonnet components, electrical interfaces and parts with high resistance to temperature and media.

What makes PBT distinctive?
PBT is one of the engineering thermoplastics and is used where dimensional stability, electrical properties, and resistance come together. Price series make price series and regions straightforward to compare.
Technical properties
PBT combines high dimensional stability with good electrical properties and broad scope for formulation. Glass-fibre reinforced grades widen the range of applications.
- Dimensional stability: PBT suits precision components and tight tolerances.
- Electrical properties: the material is relevant for connectors, switches, and insulation applications.
- Reinforceable grades: glass-fibre reinforced PBT grades raise stiffness and heat deflection temperature.
Market relevance
PBT price data matters for engineering sectors in which material approvals, specifications and quality requirements are closely interlinked.
- E&E focus: many applications lie in electrical engineering, connector technology, and appliance segments.
- Automotive relevance: components in the vehicle environment require predictable material costs.
- Variant logic: natural, black and GF grades can show different price levels.
Processing methods
PBT is processed above all where technical precision and stable component properties are required. Particularly important are:
- Injection moulding: for connectors, housings, switches, and technical moulded parts.
- Compounding: for glass-fibre reinforced or additivated grades with defined properties.
- Extrusion: for selected profiles, semi-finished products, and technical applications.
