Complete Guide on PBT (Polybutylene Terephthalate): Grades, Uses, Properties, Market & More

1. What is PBT?

PBT (Polybutylene Terephthalate) is a semi-crystalline thermoplastic polyester engineered for high performance. It belongs to the same family as PET but has faster crystallization and better dimensional stability.

Commonly used in electrical insulation, automotive parts, and precision components, PBT is known for:

• High mechanical strength

• Excellent heat and chemical resistance

• Superior electrical properties
