Both PET (Polyethylene Terephthalate) and PBT (Polybutylene Terephthalate) are thermoplastics produced through the process of polycondensation. They belong to the category of high-performance materials known as engineering plastics.

Due to its faster crystallization rate, PBT is particularly well-suited for injection moulding applications. It offers an excellent balance of stiffness and strength, along with good toughness, heat resistance, and dimensional stability—even under demanding conditions.

These properties make PBT compounds highly valuable in industries such as electronics and electrical, automotive, and aerospace.

The material’s performance can be further enhanced by incorporating reinforcements, fillers, flame retardants, and elastomer modifications, allowing it to meet specific application requirements and achieve customized property profiles.
