PBT
Polybutylene Terephthalate

Polybutylene Terephthalate (PBT) is a high-performance thermoplastic polymer known for its strength, rigidity and dimensional stability. It has excellent resistance to chemicals, heat and impact, making it suitable for a wide range of industrial and consumer applications. PBT can be easily injection-molded, extruded and thermoformed, and it is non-toxic and flame-retardant. PBT is a modified version of PET (Polyethylene Terephthalate) and it has been known for its superior mechanical and thermal properties over other plastics.

PBT was first developed in the 1930s, but it wasn’t until the 1950s that it was first commercialized by the company ICI (Imperial Chemical Industries) under the brand name Radel. and has since become a widely used engineering thermoplastic. The material was first used in the automotive industry and has since been adopted by a wide range of industries such as electrical and electronic, consumer goods, and industrial applications.
