What is PBT Plastic Material - 2002-2

As the plastics industry continues to evolve towards high performance and versatility, polybutylene terephthalate (PBT plastic material) has gained wide application in the electrical and electronic, automotive and industrial sectors due to its excellent overall performance. PBT 2002-2 from Celanese is a typical general-purpose pellet material with non-reinforced, internally lubricated properties to meet diversified injection moulding needs.

PBT 2002-2 adopts a granular form and supports the injection molding process. The flame retardant grade of the material is HB. It is equipped with lubricants and mold release agents, which makes the product molding process more stable and ensures a high surface finish. It has medium fluidity and is suitable for injection molded parts with various complex structures, especially for application scenarios that require internal lubrication and balanced processing performance.
