PBT is a semicrystalline engineering-grade thermoplastic that is part of the polyester family of resins. It resists moisture and a range of chemicals, and can achieve relatively high levels of izod impact strength through the use of impact modifiers.
Application: PBT can be used in highly stressed engineering parts in a wide variety of industrial areas. Its high stiffness and strength combined with good heat aging performance and chemical resistance allows it to replace some metal parts in automotive applications.
