Glass fiber reinforced PBT compound is a type of thermoplastic material that is reinforced with glass fibers. PBT stands for polybutylene terephthalate, which is a type of polyester material that has good mechanical, thermal, and electrical properties. The addition of glass fibers to PBT enhances its strength, stiffness, and dimensional stability. Glass fiber reinforced PBT compound is commonly used in the manufacturing of automotive parts, electrical components, and consumer goods.
