Introduction

Polybutylene Terephthalate (PBT) is a engineering thermoplastic in the polyester family. Its semi crystalline structure delivers outstanding dimensional stability, excellent heat resistance, and low moisture absorption. Known for its well balanced combination of mechanical strength, thermal stability, and resistance to a wide range of chemicals.

PBT offers high tensile and flexural strength, combined with notable wear and abrasion resistance. It exhibits superior heat aging performance, maintaining properties under prolonged thermal exposure. The polymer resists fuels, lubricants, and many common solvents, absorbs minimal moisture, and maintains reliable electrical insulation and dielectric strength. Its molding behavior enables smooth, glossy surface finishes, uniform coloration, and high precision in machined or molded components.

These performance characteristics make PBT a versatile material choice for demanding applications — from automotive structural and under hood components, to electrical connectors and housings, medical device parts that meet applicable standards, and durable household appliance components requiring long term heat resistance and reliable electrical insulation.
