Formula: PBT
Form: Rod
Material: Polybutylene terephthalate (PBT)
CAS Number: 24968-12-5
Commodity: Polymers
PBT Rods are part of our wide range of engineering plastic rods. PBT or polybutylene terephthalate, to give it its full name, is a semi-crystalline thermoplastic known for its dimensional stability, chemical resistance and electrical insulating properties. With 36 variations available, our PBT Rods come in multiple diameters and lengths to suit a wide range of applications. Example uses include electrical insulators, mechanical parts, and automotive components where heat and chemical resistance are required. Our PBT Rods provides engineers and designers with a versatile, high-performance thermoplastic material.
