Polybutylene TerephtHalate (PBT) Compounds
High-quality PBT compounds
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer. Because of its strong mechanical, thermal, and electrical properties, it is especially suited for many industrial applications. For example, you can use it in telecommunications (OFC), automotive, electronics and electrical-engineering products.
Moreover, PBT is very versatile. It can be tailored to meet specific application needs, which makes it a critical material in modern engineering and manufacturing.
