Additional Information
Polybutylene terephthalate (PBT) is a high-performance engineering thermoplastic known for its excellent dimensional stability and resistance to deformation under heat and load. This makes it ideal for applications requiring precise tolerances and reliable performance in demanding environments. Additionally, PBT offers good chemical resistance to various solvents and oils, expanding its use in industrial and medical applications.
PBT exhibits good electrical insulation properties, making it suitable for electrical components and connectors. Certain grades are inherently flame retardant, meeting stringent fire safety requirements. Its low moisture absorption contributes to its use in sensitive electronic applications and hygroscopic environments.
However, PBT can be more expensive than some other thermoplastics. It may also have lower impact resistance compared to some other materials.
