About the Product Family

CELANEX® and CRASTIN® from Celanese are semi-crystalline saturated polyesters based on polybutylene terephthalate. The manufacturer's PBT also includes the semi-crystalline, unsaturated PBT compound PIBITER®. CELANEX® and CRASTIN® are characterised by high strength, hardness and rigidity and good creep strength, even at higher temperatures. Moreover, they show excellent dimensional stability, low moisture absorption and high insulation resistance. Accordingly, CELANEX® and CRASTIN® from Celanese have very good electrical properties.

In addition, they are resistant to many chemicals, solvents, oils and greases. The extensive PBT range from Celanese offers a large selection for many different technical applications, requirements and plastics processing methods. For example, they are used as electrical connectors or in the engineering industry.
