Celanex

Brand information

Celanex® thermoplastic polyester (PBT) is a semicrystalline structure based on polybutylene terephthalate that provides high strength, rigidity and toughness, low creep even at high temperatures and resistance to a wide range of chemicals, solvents, oils and greases.

Celanex PBT material is especially suited as a sliding partner for Hostaform®/Celcon® POM plastic. PBT material features excellent dimensional stability, low moisture absorption and powerful insulation resistance.

PBT Material Properties

• Very hard, rigid & strong

• Good creep resistance

• High heat-distortion temperature, especiallty for glass-fiber reinforced grades

• Service temperature to 140°C

• Very good low-friction & wear-resistant properties

• High dimensionally stability (low thermal expansion coefficient, low water absorption)

• Good electrical properties

• Good chemical resistance

• no environmental stress cracking

• Good weathering resistance

• Rapid crystallization & fast cycle time

• Paintable

• Flame-retardant grades available (UL 94 V-0, in some cases 5VA)

Depending on market requirements, the Celanex PBT flame-retardant system is low in migration and halogen-free.
