Polybutylene TerephtHalate (PBT) Compounds
High-quality PBT compounds
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer with strong mechanical, thermal and electrical properties. These characteristics make PBT Compounds suitable for demanding applications where dimensional stability, strength and reliable performance are important.
HEC-Holland supplies high-quality PBT Compounds for different cable projects and industrial applications. Our materials can be used in applications where consistent performance and reliable processing are essential.
PBT is a versatile material that can be tailored to meet specific application requirements. Therefore, the right grade can be selected according to the cable construction, production process and required material properties.
Reliable performance and easy processing
PBT offers a combination of mechanical strength, thermal resistance and dimensional stability. It has high tensile strength and good impact resistance, including at low temperatures. In addition, PBT has good resistance to oils, greases, solvents and many chemicals.
The material also offers good creep behaviour and a low tendency to stress cracking. Depending on the grade and application, PBT can maintain its mechanical performance across a wide temperature range.
PBT Compounds are also well suited to conventional processing methods such as injection moulding and extrusion. Their good viscosity and fast crystallisation can support efficient processing and high production speeds.
Applications
PBT Compounds are used in a wide range of applications. Within the cable industry, they are particularly suitable for optical fibre cable constructions and other applications where reliable dimensional stability and mechanical performance are required.
PBT is also used in telecommunications, automotive, electronics and electrical engineering products. The right PBT grade depends on the specific application and the required combination of mechanical, thermal, electrical and chemical properties.
